Abstract
We have investigated the structural, magnetic and electrical transport properties of the Ni doped FeRh films prepared by magnetron co-sputtering. A large magetoresistance of 35%, induced by a reversible antiferromagnetic to ferromagnetic phase transition, is obtained at room temperature with only 1â¯mol.% Ni addition. Magnetic field is revealed to have an equivalent effect as temperature to drive the magnetic phase transition. Moreover, the way to realize a nonvolatile room temperature magetoresistance effect is also discussed. These results give FeRh the possibility of technological application in the spintronic field at room temperature, which are referential to other material systems with a first-order magnetic phase transition.
