Özet
The present study investigated the magnetic hysteresis properties (coercivity and remanent
magnetization) of the Zr2RhTl Heusler alloy using effective field theory (EFT). The study
found that the coercive field of Zr2RhTl reaches a maximum at a specific critical temperature,
Tch, at which the hardness of magnetic materials increases with the coercive field. This
behavior is called the “critical hardness temperature (Tch)”. The hardness of the Zr2RhTl
Heusler alloy increases with temperature until Tch, reaching a maximum at Tch. In contrast,
it exhibits soft magnetic behavior at T < Tch and T > Tch. We suggest that this maximum
hardness behavior can enable a new class of thermo-hardness sensors (THSs) and actuators
(THAs).
