Abstract

Mn{sub 1.5}X{sub 0.5}Sn (X = Cr, Mn, Fe, Co) nanomaterials in the hexagonal Ni{sub 2}In-type crystal structure have been prepared using arc-melting and melt spinning. All the rapidly quenched Mn{sub 1.5}X{sub 0.5}Sn alloys show moderate saturation magnetizations with the highest value of 458 emu/cm{sup 3} for Mn{sub 1.5}Fe{sub 0.5}Sn, but their Curie temperatures are less than 300 K. All samples except the Cr containing one show spin-glass-like behavior at low temperature. The magnetic anisotropy constants calculated from the high-field magnetization curves at 100 K are on the order of 1 Merg/cm{sup 3}. The vacuum annealing of the ribbons at 550 °C significantly improved their magnetic properties with the Curie temperature increasing from 206 K to 273 K for Mn{sub 1.5}Fe{sub 0.5}Sn.

Structural, magnetic, and electron transport properties of Mn{sub 3−x}Pt{sub x}Sn (x = 0, 0.5, 1) nanomaterials

Journal Article Nelson, A. ; Huh, Y. ; Kharel, P., E-mail: parashu.kharel@sdstate.edu ; ... - Journal of Applied Physics

The structural, magnetic, and electron-transport properties of Mn{sub 3−x}Pt{sub x}Sn (x = 0, 0.5, 1) nanomaterials prepared by arc-melting, melt-spinning, and annealing were investigated. It was found that the hexagonal structure is the most stable structure for Mn{sub 3}Sn and the samples show an antiferromagnetic spin order at room temperature. The Pt-containing samples are mainly tetragonal but contain a small amount of other impurity phases, including hexagonal Mn{sub 3}Sn and Mn{sub 2}Sn. At room temperature, the Pt-containing samples show ferri- or ferromagnetic spin order with a Curie temperature of about 370 K. The measured high-field magnetization and anisotropy constant for Mn{sub 2}PtSn are 405 emu/cm{supmore »« less

Phase evolution and magnetocaloric effect of melt-spun Mn{sub 3}Sn{sub 2-xM{sub x}} (M = B, C; x = 0-0.5) ribbons

Journal Article Zhao, X. G. ; Shenyang National Laboratory for Materials Science, Institute of Metal Research, and International Centre for Materials Physics, Chinese Academy of Sciences, Shenyang 110016 ; Lee, E. H. ; ... - Journal of Applied Physics

The effects of B and C substitution for Sn on phase components, Curie temperature T{sub C}, and magnetocaloric effect of melt-spun Mn{sub 3}Sn{sub 2-x}M{sub x} (M B, C; x = 0-0.5) ribbons have been investigated. X-ray diffraction (XRD) results show that the main phase in the as-spun Mn{sub 3}Sn{sub 2-xM{sub x}} (M = B, C; x 0-0.5) ribbons is Mn{sub 3}Sn{sub 2} of Ni{sub 3}Sn{sub 2}-type (Pnma). Minor Mn{sub 2}B (when x {>=} 0.1) or Mn{sub 5}C{sub 2} (when x > 0.1) secondary phase is formed, and their amounts increase with increasing B and C concentration, respectively.

Extraordinarily large perpendicular magnetic anisotropy in epitaxially strained cobalt-ferrite Co{sub x}Fe{sub 3−x}O{sub 4}(001) (x = 0.75, 1.0) thin films

Journal Article Niizeki, Tomohiko ; Utsumi, Yuji ; Aoyama, Ryohei ; ... - Applied Physics Letters

Perpendicular magnetic anisotropy (PMA) of cobalt-ferrite Co{sub x}Fe{sub 3-x}O{sub 4} (x = 0.75 and 1.0) epitaxial thin films grown on MgO (001) by a reactive magnetron sputtering technique was investigated. The saturation magnetization was found to be 430 emu/cm{sup 3} for x = 0.75, which is comparable to that of bulk CoFe{sub 2}O{sub 4} (425 emu/cm{sup 3}). Torque measurements afforded PMA constants of K{sub u}{sup eff}=9.0 Merg/cm{sup 3} (K{sub u}=10.0 Merg/cm{sup 3}) and K{sub u}{sup eff}=9.7 Merg/cm{sup 3} for x = 0.75 and 1.0, respectively. The value of K{sub u}{sup eff} extrapolated using Miyajima's plot was as high as 14.7more »« less

Effect of Fe substitution on the structural, magnetic and electron-transport properties of half-metallic Co ₂TiSi

Journal Article Jin, Y. ; Waybright, J. ; Kharel, P. ; ... - AIP Advances

The structural, magnetic and electron-transport properties of Co ₂Ti _1-xFe _xSi (x = 0, 0.25, 0.5) ribbons prepared by arc-melting and melt-spinning were investigated. The rapidly quenched Co ₂Ti _0.5Fe _0.5Si crystallized in the cubic L2 ₁ structure whereas Co ₂Ti _0.75Fe _0.25Si and Co ₂TiFe ₀Si showed various degrees of B2-type disorder. At room temperature, all the samples are ferromagnetic, and the Curie temperature increased from 360 K for Co ₂TiSi to about 800 K for Co ₂Ti _0.5Fe _0.5Si. The measured magnetization also increased due to partial substitution of Fe for Ti atoms. The ribbons are moderately conductingmore »« less
