Determine switching and transport properties of near-degenerate AT6X6 magnets

Determine the switching fields, activation barriers, spin-orbit torque efficiencies, and state-dependent transport properties of the near-degenerate LiFe6Ga6, MgFe6Ga6, TiMn6Ge6, and TiFe6Ga6 magnetic configurations.

Background

The calculations identify several AT6X6 compounds in which ferromagnetic, antiferromagnetic, long-period, and finite-angle magnetic configurations are separated by only a few meV per transition-metal atom. Such energetic proximity suggests that magnetic fields or electrical currents might reconfigure the layer alignment, making these compounds potential candidates for spintronic switching.

The paper does not calculate the relevant device-level quantities. In particular, switching fields, activation barriers, torque efficiencies, and transport responses remain unresolved and require synthesis, magnetic-structure determination, and field- or current-dependent measurements.
