Structural Dependent Ferromagnetic-Nonmagnetic Phase Change in FePtRu Films

Figure 3

Magnetic properties of the FePt_1−xRu_x films after annealing at 1173 K for 4 h. Magnetization curves of the ordered FePt_1−xRu_x films with = (a) 0, (b) 0.10, (c) 0.20, (d) 0.40, and (e) 0.60. was applied perpendicular (⊥, filled symbols) and parallel (//, open symbols) to the film plane at 298 K. (f) -dependence of and at 298 K.
