Title: ¹⁵¹Eu Mössbauer study of magnetic ordering in flux-grown ferromagnetic and antiferromagnetic forms of EuCd₂As₂

Abstract

EuCd₂As₂ is a remarkably complex magnetic semimetal that may behave as a topological insulator or host two pairs of Weyl points, depending on the growth conditions and the final magnetic state. Both antiferromagnetic (AFM) and ferromagnetic (FM) forms have been grown, and we show here, using ¹⁵¹Eu Mössbauer spectroscopy, that the differences between the AFM and FM forms extend well beyond their ground state magnetic structures. Whereas the AFM form undergoes a conventional AFM → paramagnetic transition on warming, the FM form passes through a complex incommensurate modulated state before becoming paramagnetic.

Pressure-induced ferromagnetism in the topological semimetal $Eu {Cd}_{2} {As}_{2}$

Journal Article Gati, Elena ; Bud'ko, Sergey L. ; Wang, Lin-Lin ; ... - Physical Review B

The antiferromagnet and semimetal EuCd₂As₂ has recently attracted a lot of attention due to a wealth of topological phases arising from the interplay of topology and magnetism. In particular, the presence of a single pair of Weyl points is predicted for a ferromagnetic configuration of Eu spins along the c axis in EuCd₂As₂. In the search for such phases, we investigate here the effects of hydrostatic pressure in EuCd₂As₂. For that, we present specific heat, transport, and μSR measurements under hydrostatic pressure up to ~2.5GPa, combined with ab initio density functional theory (DFT) calculations. Experimentally, we establish that the groundmore »« less

Magnetic and structural transitions in EuAg₄As₂ studied using ¹⁵¹Eu Mössbauer spectroscopy

Journal Article Ryan, D. H. ; Bud’ko, Sergey L. ; Hu, Chaowei ; ... - AIP Advances

¹⁵¹Eu Mössbauer spectroscopy confirms that the europium in EuAg₄As₂ is fully divalent and that the spectrum at 5 K consists of a single, sharp magnetic pattern with a hyperfine field (B_hf) of 27.1(1) T and an isomer shift of -11.04(3) mm/s (relative to EuF₃). The temperature dependence of the spectra shows that the ordering of the Eu moments proceeds via an incommensurate sine modulated structure starting at 15 K. The structure squares up below 9 K. A search for charge density or phonon softening signatures at the 120 K structural transition was not successful

SrAgZn and EuAgZn with KHg{sub 2}-type structure—Structure, magnetic properties, and {sup 151}Eu Mössbauer spectroscopy

Journal Article Gerke, Birgit ; Rodewald, Ute Ch. ; Niehaus, Oliver ; ... - Journal of Solid State Chemistry

Samples of SrAgZn and EuAgZn were synthesized by reaction of the elements in sealed tantalum crucibles. Both structures were refined on the basis of single crystal X-ray diffractometer data: KHg{sub 2}-type, Imma, a=476.7(1), b=780.9(2), c=810.1(2) pm, R{sub 1}/wR{sub 2}=0.0189/0.0119, 381 F² values for SrAg{sub 1.12}Zn{sub 0.88} and a=474.43(9), b=760.8(2), c=799.0(2) pm, R{sub 1}/wR{sub 2}=0.0226/0.0483, 370 F² values for EuAg{sub 1.17}Zn{sub 0.83} with 13 variables per refinement. Silver and zinc are randomly distributed on the Hg position and build up three-dimensional networks. EuAgZn shows ferromagnetic ordering at 29(1) K.

Complex magnetic ordering in EuAl₄–A ¹⁵¹Eu Mössbauer study

Journal Article Ryan, Dominic H. ; Kuthanazhi, Brinda ; Jo, Na Hyan ; ... - AIP Advances

¹⁵¹Eu Mössbauer spectroscopy has been used to investigate the behaviour of EuAl₄ through the four magnetic transitions that occur below 16 K. We find clear evidence for the first transition (T_N1, the onset of order) where an incommensurate modulated magnetic structure appears, and the third (T_N3) where the modulation disappears at the tetragonal → orthorhombic structural transition. We see no changes at the lowest transition (T_N4) but find that the modulation amplitude passes through a maximum at T_N2. Data on the isostructural but magnetically simpler EuGa₄ are also presented for comparison.

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
