Magnetism of hexagonal Mn1.5X0.5Sn (X = Cr, Mn, Fe, Co) nanomaterials
نویسندگان
چکیده
nanomaterials in the hexagonal Ni 2 In-type crystal structure have been prepared using arc-melting and melt spinning. All the rapidly quenched Mn 1.5 X 0.5 Sn alloys show moderate saturation magnetizations with the highest value of 458 emu/cm 3 for Mn 1.5 Fe 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 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 1.5 Fe 0.5 Sn.

Magnetism and magnetocrystalline anisotropy of 3dtransition metal monolayers on Pt(001): a density-functional study.
We systematically investigate the effects of having Pt as a substrate and/or capping layer on the magnetism and magnetocrystalline anisotropy (MCA) of 3d transition metal (TMs; Cr, Mn, Fe, and Co) monolayers (MLs) by using a first-principles calculationl method. We found that Fe and Co MLs are ferromagnetic (FM) on a Pt(001) surface, but Mn and Cr MLs are antiferromagnetic (AFM). The magnetic m...

ZnO structures with different dopants (1mol% Cr, Mn, Fe, Co, Cu and Ni) have been synthesized via a simple hydrothermal method using sucrose as a template. These doped ZnO nanostructures characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL). The photocatalytic property of these synthesized materials was studied by a pho...

Powder samples and single crystals of the boride phases MxRh7−xB3 (M = Cr, Mn, Ni; x≤ 1) have been synthesized from the elements using an arc-melting furnace under purified argon atmosphere in a water-cooled copper crucible. The new phases were characterized from single-crystal and powder X-ray diffraction, as well as semi-quantitative EDX measurements. The obtained phases crystallize in the he...
متن کاملSpin configuration in a frustrated ferromagnetic/antiferromagnetic thin film system
We have studied the magnetic configuration in ultrathin antiferromagnetic Mn films grown around monoatomic steps on an Fe(001) surface by spin-polarized scanning tunneling microscopy/spectroscopy and ab-initio-parametrized self-consistent real-space tight binding calculations in which the spin quantization axis is independent for each site thus allowing noncollinear magnetism. Mn grown on Fe(00...
متن کاملMagnetism of 3d transition-metal monolayers on Rh(100)
We employ the full-potential linearized augmented plane-wave method to report a systematic density-functional theory study of the magnetic properties of the 3d transition-metal (V, Cr, Mn, Fe, Co, and Ni) monolayers deposited on the Rh(100) substrate. We find that all monolayer films are magnetic. The size of the local magnetic moments across the transition-metal series follows Hund’s rule with...
