Abstract
FePtRh films with different Rh concentrations (FePt1–x Rh x ) are fabricated by magnetron sputtering. The magnetic structure and ferromagnetic–paramagnetic phase transition in thin films of L10 FePt1–x Rh x with different Rh concentrations (0 ≤ x ≤ 0.40) are studied. It is demonstrated that thin films of FePt1–x Rh x with 0 < x < 0.34 are in the ferromagnetic state with high magnetocrystalline anisotropy energy at room temperature, while similar films with 0.34 < x < 0.4 are paramagnetic.
