and related ternary metallic perovskites with perpendicular anisotropy are interesting for spintronics, but their magnetic structures differ from the triangular ferrimagnetism of the bulk. A ...
Au4Mn: A localized ferromagnet with strong spin-orbit coupling, long-rangeferromagnetic exchange, and high Curie temperature
(2022)
Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal

Influence of topology on the phase transition of a ferromagnetic metal
(2023)
The topological ferromagnet CoS2 exhibits an anhysteretic, weakly first-order transition at the Curie temperature of 119.8 K with a tricritical point µ0Htcp at 0.034 T. Magnetic symmetry and the mixing of majority and ...
Stability of Mn2RuxGa-based Multilayer Stacks, Gwenaël Atcheson, Katarzyna Siewierska, J. M. D. Coey, Karsten Rode, Plamen Stamenov
(2022)
Perpendicular heterostructures based on a ferrimagnetic Mn2RuxGa (MRG) layer and a ferromagnetic Co/Pt multilayer were examined to understand the effects of different spacer layers (V, Mo, Hf, HfOx and TiN) on the interfaces ...
Effect of insertion layer on electrode properties in magnetic tunnel junctions with a zero-moment half-metal
(2019)
Due to its negligible spontaneous magnetization, high spin polarization and giant perpendicular
magnetic anisotropy, Mn2RuxGa (MRG) is an ideal candidate as an oscillating layer in THz spin-transfertorque nano-oscillators. ...
History of Magnetism and Basic Concepts
(Springer, Cham, 2021)
Magnetism is a microcosm of the history of science over more than two millennia. The magnet allows us to manipulate a force field which has catalyzed an understanding of the natural world that launched three revolutions. ...
Single-pulse all-optical switching in amorphous DyxCo1-x and TbxCo1-x
(2022)
Repeated uniform switching of the magnetization of thin films of ferrimagnetic amorphous Gdx(FeCo)1−x in response to single fast laser pulses is well established. Here, we report unusual toggle switching in thin films of ...
Sub-picosecond exchange-relaxation in the compensated ferrimagnet Mn2RuxGa
(2021)
We study the demagnetization dynamics of the fully compensated half-metallic ferrimagnet Mn2RuxGa. While the two antiferromagnetically coupled sublattices are both composed of manganese, they exhibit different temperature ...
Metallic Nitride and Carbide Perovskites: History and Prospects
(2022)
Energy-level diagrams for cubic metallic Fe4N and Mn4N were proposed by Goodenough in the late 1960s. Fe4N is ferromagnetic, but Mn4N is ferrimagnetic with a large moment on Mnc at the cube corner site and a much smaller ...
Reversible hydrogen control of antiferromagnetic anisotropy in α-Fe2O3
(2021)
Antiferromagnetic insulators are a ubiquitous class of magnetic materials, holding the promise of low-dissipation spin-based computing devices that can display ultra-fast switching and are robust against stray fields. ...
