Magnetoresistance of Fe-Rh metamagnetic alloy

Potentiometric method was used for investigating Fesub(0.49)Rhsub(0.51) alloy magnetoresistance and magnetization was measured by a vibration magnetometer. Sharp magnetization growth was detected when reaching a critical field value which testify to the presence of antiferromagnetic-ferromagnetic transition (HF-F). It turned out to be possible to induce irreversible ferromagnetic state in some temperature range below Tb i.e. in afinterromagnetic state. This temperature range for aloy under investigation is from 315 to 325 K
