摘要：
Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 degrees C are saturation magnetization 9.13 x 10(5) A/m, coercivity 79.6 A/m, out-of-plane uniaxial anisotropy field 1.59 x 10(3) A/m, and electrical resistivity 3.75 mu Omega.m. Based on these excellent properties, we employed such films to fabricate magnetic thin film inductor. The performance of the high entropy alloy thin film inductors is superior to that of air core inductor.
