Abstract

Fe{sub 2}Mn{sub 1-x}Cr{sub x}Si (x = 0, 0.1, and 0.2) alloys were investigated for their magnetic and transport properties in view of the expected half metallicity. It is found that Cr substitution suppresses the antiferromagnetic phase present in parent Fe{sub 2}MnSi, which completely disappears for x = 0.2. Curie temperature of the alloys increases from 230 K to 299 K as x is increased from 0 to 0.2. The value of the Rhodes-Wohlfarth ratio indicates that the system shows iterant magnetism. Resistivity measurements also show absence of antiferromagnetic phase for x = 0.2. Resistivity data have been fitted by considering the electron-phonon and electron-magnon scattering contributions, which indicates the presence of half metallicity in these compounds. Temperature dependence of resistivity data shows magnetoresistance of −3% and −2.5% at Curie temperature with applied field of 50 kOe for x = 0.1 and 0.2, respectively.

Non-Fermi-liquid types of behavior associated with a magnetic quantum critical point in $Sr {({Co}_{1 - x} {Ni}_{x})}_{2} {As}_{2}$ single crystals

Journal Article Sangeetha, N.; Wang, L.; Smirnov, A.; ... - Physical Review B

The compound SrCo₂As₂ with the body-centered tetragonal ThCr₂Si₂ structure is known to remain paramagnetic down to a temperature T = 0.05 K, but inelastic neutron scattering studies have shown that both ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations occur in single crystals. Thus it is of interest to study how the magnetism evolves on doping SrCo₂As₂. Previous work on polycrystalline samples of Sr (Co_1-x Ni_x)₂ As₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co_1-x Ni_x)₂ As₂ for 0 < x ≤ 1 and confirmed the occurrence of AFM order whichmore »« less

Comparison of magnetic and electrical properties of amorphous (Fe sub 1 minus x M sub x ) sub 75 Si sub 15 B sub 10 : M =Co, Cr

Journal Article Bhatnagar, A; Rao, G; Munirathnam, N - Journal of Applied Physics; (United States)

Amorphous (Fe{sub 1{minus}{ital x}}{ital M}{sub {ital x}}){sub 75}Si{sub 15}B{sub 10} ({ital M}=Co, Cr and 0.00{le}{ital x}{le}0.12) metallic glasses have been investigated using Fe{sup 57} Moessbauer spectroscopy and electrical resistivity measurements. With Co substitution, hyperfine magnetic field ({ital H}{sub eff}) decreases initially and then levels off, whereas Curie temperature ({ital T}{sub {ital c}}) initially increases before leveling off. Chromium substitution results, however, in a substantial decrease of {ital H}{sub eff} ({similar to}6.5 kOe/at. % of Cr) and {ital T}{sub {ital c}} ({similar to}30 K/at. % of Cr). Hyperfine field distribution {ital P}({ital H}) for Fe{sub 75}Si{sub 15}B{sub 10} does not changemore »« less

Effect of composition on Curie temperature, magnetic moment, and high-field susceptibility of amorphous Fe sub 90 minus x M x Zr sub 10 ( M =V, Cr, Mn, Co, Ni, Cu, Si, and B) alloys

Journal Article Bao-gen, S; Rufeng, X; Jian-gao, Z; ... - Physical Review, B: Condensed Matter; (USA)

Magnetization measurements for amorphous Fe{sub 90{minus}{ital x}M{ital x}}Zr{sub 10} ({ital M}=V, Cr, Mn, Co, Ni, Cu, Si, and B) alloys prepared by single-roller spin quenching have been made by an extracting sample magnetometer in magnetic fields up to 65 kOe and at temperatures ranging from 1.5 to 300 K. Preliminary results show that the magnetic properties of these amorphous alloys strongly depend upon the {ital M} concentration and display a similarity to those of the parent Fe-Zr base; compared with amorphous Fe-{ital M}-B alloys with the same concentration, all the samples are characterized by a large high-field susceptibility, a smallmore »« less

The structure, magnetism, and electrical-transport properties of the Heusler alloys Co{sub 2}Cr{sub 1-x}Fe{sub x}Al (x=0.2-0.6)

Journal Article Ming, Zhang; Wolf, Anne; Zhang, L; ... - Journal of Applied Physics

We synthesize the polycrystalline Heusler compounds Co{sub 2}Cr{sub 1-x}Fe{sub x}Al (x=0.2-0.6). The x-ray diffraction patterns show A2 structure rather than L2{sub 1} structure. The magnetic moment and the Curie temperature increase with increasing x. The electrical resistivity characterizes the Co{sub 2}Cr{sub 1-x}Fe{sub x}Al compounds to be not typical metals and the temperature dependence of the resistivity changes from metallic to semiconductinglike behavior with increasing Cr concentrations. We attribute the fact, which we observe for most of the compounds smaller magnetic moments than the theoretical values and the low magnetoresistance in these alloys, to the considerably high level of Co-(Cr, Fe)-typemore » disorder.« less

Effects of Cr substitution on the formation, structure and magnetic properties of Sm{sub 2}(Fe,Cr){sub 17}C{sub x} alloys

Journal Article Chen, Z; Hadjipanayis, G - IEEE Transactions on Magnetics

The effects of Cr substitution on the formation, structure and magnetic properties of Sm{sub 2}(Fe,Cr){sub 17}C{sub x} alloys have been systematically studied on arc-melted and melt-spun samples using XRD, TEM and magnetic measurements. It has been found that Cr substitution is an effective way to form the Sm{sub 2}(Fe,Cr){sub 17}C{sub x} carbides. The minimum amount of Cr needed to form an almost single 2:17 structure is around x = 2. Magnetic measurements reveal that the Cr substituted Sm{sub 2}(Fe,Cr){sub 17}C{sub x} carbides have a strong uniaxial magnetocrystalline anisotropy with anisotropy fields higher than 90 kOe obtained in both the Sm{submore »« less
