Abstract

The ferromagnetic superconductor Y₉Co₇ was chemically doped to yield the solid solution Y₉Co_7-xPd_x for 0 < x < 0.4. The lattice parameter a does not depend on x, whereas c increases with increasing Pd content up to x = 0.2, the palladium solubility limit. The transition from ferromagnetism (T_C = 4.25 K) to superconductivity (T_sc = 2.4 K) was observed only for the parent Y₉Co₇ compound. For the lowest tested Pd doping level (x = 0.05), ferromagnetism is enhanced strongly (T_C = 9.35 K) and superconductivity is not seen above 1.8 K. Finally, the Curie temperature rapidly increases from 4.25 K to about 10 K for a Pd concentration of x = 0.1 and remains almost unchanged for Y₉Co_6.8Pd_0.2.

Suppression of antiferromagnetic order and strong ferromagnetic spin fluctuations in Ca(Co_1-xNi_x)_2-y As₂ single crystals

Journal Article Pakhira, Santanu ; Lee, Y. ; Ke, Liqin ; ... - Physical Review B

CaCo_2–yAs₂ is a unique itinerant system having strong magnetic frustration. Here, we report the effect of electron doping on the physical properties resulting from Ni substitutions for Co. The single crystals of Ca(Co_1–xNi_x)_2–y As₂ were characterized by single-crystal x-ray diffraction, energy-dispersive x-ray spectroscopy, magnetization M versus temperature T, magnetic field H, time t, and heat capacity C_p (H, T) measurements. The A-type antiferromagnetic (AFM) transition temperature T_N = 52 K for x = 0 decreases to 22 K with only 3% Ni substitution and is completely suppressed for x > 0.16. For 0.11 ≤ x ≤ 0.52 strong ferromagnetic (FM)more »« less

Weak ferromagnetism of $Cu_{x} Fe_{1 + y} As$ and its evolution with Co doping

Journal Article Qian, Bin ; Hu, Jin ; Liu, Jinyu ; ... - Physical Review. B, Condensed Matter and Materials Physics

We have investigated electronic and magnetic properties of iron pnictide Cu_xFe_1+yAs, which is isostructural to iron pnictide superconductors LiFeAs and NaFeAs, using polycrystalline and single crystal samples. Here, we found that Cu_xFe_1+yAs is characterized by strong electron correlations and shows weak ferromagnetic behavior with the Curie temperature T_c ~ 42 K, in contrast with the superconductivity in LiFeAs and NaFeAs. Its electronic transport properties exhibit quasi-two-dimensional characteristics: while the in-plane resistivity follows quadratic temperature dependence for T < 10K, the c-axis resistivity shows nonmetal-to-metal crossover near 20 K. In addition, we have studied Co doping effect on Cu_xFe_1+yAs and foundmore »« less

Magnetic phase transitions in Eu(Co_1-xNix)_2-yAs₂ single crystals

Journal Article Sangeetha, N. S. ; Pakhira, Santanu ; Ryan, D. H. ; ... - Physical Review Materials

The effects of Ni doping in Eu(Co_1-xNi_x)_2-yAs₂ single crystals with x = 0 to 1 grown out of self flux are investigated via crystallographic, electronic transport, magnetic, and thermal measurements. All compositions adopt the body-centered-tetragonal ThCr₂Si₂ structure with space group I4=mmm. Here, we also find 3-4% of randomly-distributed vacancies on the Co/Ni site. Anisotropic magnetic susceptibility _{more » $$\chi$$α} (α = ab; c) data versus temperature T show clear signatures of an antiferromagnetic (AFM) c-axis helix structure associated with the Eu⁺² spins-7/2 for x = 0 and x = 1 as previously reported. The _$$\chi$$α(T) data for x = 0.03 and 0.10 suggest an anomalous 2q magnetic structure containing two helix axes along the c axis and in the ab plane, respectively, whereas for x = 0.75, 0.82, and 1 a c-axis helix is inferred as previously found for x = 1. At intermediate compositions x = 0:2, 0.32, 0.42, 0.54, and 0.65 a magnetic structure with a large ferromagnetic (FM) c-axis component is found from magnetization versus fi eld isotherms, suggested to be an incommensurate FM cone structure associated with the Eu spins, which consists of both AFM and FM components. In addition, the _$$\chi$$(T) and heat capacity C_p(T) data for x = 0.2-0.65 indicate the occurrence of itinerant FM order associated with the Co/Ni atoms with Curie temperatures from 60 K to 25 K, respectively. Electrical resistivity ρ(T) measurements indicate metallic character for all compositions with abrupt increases in slope on cooling below the Eu AFM transition temperatures. In addition to this panoply of magnetic transitions, ¹⁵¹Eu Mössbauer measurements indicate that ordering of the Eu moments proceeds via an incommensurate sine amplitude-modulated structure with additional transition temperatures associated with this effect.« less

Comparative study of thermal and magnetic properties of CeT{sub y}X{sub 4{minus}y} ferromagnets

Journal Article Sereni, J G ; Trovarelli, O ; Schmerber, G ; ... - Physical Review, B: Condensed Matter

Low-temperature thermal (specific heat, C{sub P}) and magnetic [ac susceptibility, {chi}{sub ac}, and isothermal magnetization M(B)] measurements on CeT{sub y}X{sub 4{minus}y} ferromagnets (with T=Ni, Cu, Pd, Ag, Au, and X=Ga, Al, with 0.3{lt}y{lt}0.7) are reported. With the exception of T=Ni, all compounds with X=Ga show a typical second-order ferromagnetic transition. In the case of T=Ni, magnetic correlations set in at T{approx}3T{sub C} (T{sub C} being the Curie temperature) and the C{sub P}(T) and {chi}{sub ac}(T) maxima (at 3.3 and 4.2 K, respectively) do not coincide, while the M(B) curves reveal an antiferromagnetic character at lower temperatures.

Ti ₃ CrCu ₄ : A possible 2-D ferromagnetic spin fluctuating system

Journal Article Dhar, S. K. ; Provino, A. ; Manfrinetti, P. ; ... - AIP Advances

Ti₃CrCu₄ is a new ternary compound which crystallizes in the tetragonal Ti₃Pd₅ structure type. The Cr atoms form square nets in the a-b plane (a = 3.124 Å) which are separated by an unusually large distance c = 11.228 Å along the tetragonal axis, thus forming a -2-D Cr-sublattice. The paramagnetic susceptibility is characterized by a low effective moment, μ_eff = 1.1 μ_B, a low paramagnetic Curie temperature θ_P (below 7 K) and a temperature independent χ0 = 6.7 x 10^–4 emu/mol. The magnetization at 1.8 K increases rapidly with field nearly saturating to 0.2 μ_B/f.u. The zero field heatmore »« less
