A direct comparison of the splitting of free exciton states with the magnetic moment of the Mn2+ ion system shows excellent agreement with simple exchange interaction model throughout the composition range studied (0.005 < x < 0.3) at liquid helium temperature in magnetic field up to 5.6 T. ...
A semimagnetic semiconductor tunneling device is proposed as a spin filter. This device, which gives spin-polarized electron current, is obtained by choosing different layers of II-VI compounds, with magnetic moments of substitutional ions ofMn2+in some of the layers. We present a theoretical calc...
In this work, by studying the spin–orbit torque induced switching in the Heusler alloy Mn2Ru1? x Ga, it is found that efficient current‐induced magnetic switching can be realized in a nearly compensated sample with strong perpendicular anisotropy and large film thickness. This work demonstrates...
Thin film samples were previously grown in (101) orientation by MBE15 and Fe/Mn2Au(101) bilayers showed AMR effects of up to 2.5% in a 14 T rotating magnetic field16. While Mn2Au was the first compound for which current-induced internal staggered spin-orbit torques were predicted3, ...
If the active site of MN2B2 had a high-spin magnetic moment (μ), it was conducive to reducing the limit potential of the NRR. Increasing the electron spin state of the M center of the active site of MN2B2 helped to break the linear proportional relationship between the adsorption energies...
Among transition metal ions, Mn2+ has received long-standing interest as a dopant in semiconductors14 because of its large spin magnetic moment (S = 5/2) and quenched orbital magnetic moment (L = 0). The latter implies reduced electron spin–lattice interactions, leading to ...
The contributions of the subsystem of dispersed Mn2+ ions, Ge3Mn5 ferromagnetic clusters, and Mn-enriched ferromagnetic domains of Ge to the magnetic moment of Ge1 − x Mn x films are distinguished. In the subsystem of dispersed Mn2+ ions in Ge1 − x Mn x films at temperatures below...
Self-consistent spin-polarized energy-band calculations have been performed for Mn2Sb for a ferrimagnetic (FI), ferromagnetic (F), and antiferromagnetic (A... JH Wijngaard,C Haas,RAD Groot - 《Physical Review B》 被引量: 30发表: 1992年 加载更多来源...
The magnetic Weyl semimetal has a Curie temperature of 177 K and a low-temperature out of the plane magnetic moment of about 0.3 μB/Co6,27,28. We employed spin-polarized STM/S to study the cleaved surface of Co3Sn2S2 (Fig. 1b). In STM topographic images, two types of cleaved sur...
