Abstract
Excellent soft magnetic properties in a wide x range with coercivity not exceeding 5.0 Oe were obtained successfully in the (Ni75Fe25) x (ZnO)1−x granular films which were fabricated by the magnetic alloy Ni75Fe25 and semiconductor ZnO. For the typical sample with x = 0.74, coercivities in hard and easy axes are 1.1 and 1.7 Oe, respectively, and the electric resistivity ρ reaches 425 μΩ cm. The dependence of complex permeability u = u ′−j u ″ on frequency f shows that the real part u ′ is more than 200 below 1.0 GHz and the ferromagnetic resonance frequency f r reaches 1.32 GHz, implying the promising for high-frequency application.
