Reversal Mechanism

The magnetic FeCoGd thin films with various sputtering power from 10 to 30 W were fabricated on glass substrates by magnetron co-sputtering. The crystal structure of as-deposited FeCoGd thin films was investigated by X-ray diffraction. And an increasing trend of grain size with the increasing sputtering power was shown. When sputtering power is below 30 W, the films exhibited obviously in-plane uniaxial magnetic anisotropy, and the in-plane magnetic anisotropy field Hkdecreased with increasing deposition power. Moreover, good high frequency characteristics were obtained. The magnetization reversal mechanism has been investigated via the in-plane angular dependences of the magnetization and the coercivity. The experimental data points indicated that the magnetization reversal mechanism of FeCoGd film with in-plane uniaxial anisotropy is domain-wall depinning and coherent rotation when the applied field is close to the easy axis and hard axis, respectively. A spin reorientation transition phenomenon was observed when deposition power is larger than 30 W. A stripe domain structure for the sample with 30 W deposition power was developed due to a dominated perpendicular magnetic anisotropy.

Influence Of Substrate

The [Fe-Co-Si (d)/native oxid50multilayer films were deposited on Kapton substrate and glass substrate by DC magnetron sputtering. The effect of substrate on magnetic and electric properties of the multilayer films was investigated. Compared to the films on glass substrates, higher coercivity, larger uniaxial-anisotropy field were achieved for the flexible films. The values of the resistivities for the flexible films are of the order of 10 mΩcm, which is two orders higher than the value of 0.1 mΩcm for the multilayer films on glass substrates. Furthermore, higher frwas found in the flexible films. It is believed that the [Fe-Co-Si (d)/native oxide]50multilayer films on flexible substrates can find its wide applications at high frequency for various purposes.
