Negative Differential Resistance and Ultra-High TMR in Altermagnetic Tunnel Junctions
Sajjan Sheoran, Luke Keenan, Declan Nell +1
Altermagnets can replace ferromagnets in tunnel junctions, yielding large tunneling magnetoresistance, ultrafast switching, and low-power functionality. While most studies explore…

Tuning spin currents in collinear antiferromagnets and altermagnets
Sajjan Sheoran, Pratibha Dev
Spin current generation through non-relativistic spin splittings, found in uncompensated magnets and d-wave altermagnets, is desirable for low-power spintronics. Such spin currents…

Spontaneous Anomalous Hall Effect in Two-Dimensional Altermagnets
Sajjan Sheoran, Pratibha Dev
The anomalous Hall effect (AHE) is an efficient tool for detecting the Néel vector in collinear compensated magnets with spin-split bands, known as altermagnets (AMs). Here, we es…
