Strain flips Hall signal in altermagnetic manganese telluride

Strain flips Hall signal in altermagnetic manganese telluride, suggesting a path to practical spintronics

Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with almost no overall magnetization. Such phases are highly…
