Multi‐Level Switching of Spin‐Torque Ferromagnetic Resonance in 2D Magnetite

Advanced Science, Volume 11, Issue 26, July 10, 2024.
The synthesis of environmentally stable and high Curie temperature 2D Fe3O4 nanosheets are reported that exhibit multi‐level resistance under the stimulation of a microwave field at room temperature. Such behavior is ascribed to the emergence of bAPBs and sAPBs in the Fe3O4 structure and morphological evolution of spin texture.

Influence of physical and material parameters on switching current density in perpendicular STT-MTJ: a micromagnetic study

Journal of Physics Communications
Switching in magnetic tunnel junctions (MTJs) is considered to be coherent according to the macrospin model but above a critical characteristic length (R _c ) this process becomes incoherent.

Epitaxial Growth of Large‐Scale 2D CrTe2 Films on Amorphous Silicon Wafers With Low Thermal Budget

Advanced Materials, Volume 36, Issue 24, June 13, 2024.
A seeded growth technique is developed for crystallizing large‐scale 2D CrTe2 films on amorphous SiNx/Si substrates with a low thermal budget. Grain boundaries, intrinsic ferromagnetism, and magnetic–electrical behavior of 2D CrTe2 magnets are controlled through crystallinity engineering.

Tuneable Vertical Hysteresis Loop Shift in Exchange Coupled La0.67Sr0.33MnO3‐SrRuO3 Bilayer

Advanced Physics Research, Volume 3, Issue 5, May 2024.
A simple method of obtaining a tuneable vertical magnetic hysteresis loop shift is demonstrated in a magnetic bilayer system. The proposed generalized model of controllable vertical shift is also applicable for other material systems possessing glassy phases, uncompensated/canted spins, absent interfacial exchange coupling, etc.
