Abstract: • The Y 2 Co 17 intermetallic compounds thin film with planar anisotropy is prepared and characterized in detail. • The Y 2 Co 17 film has saturation magnetization of 13.5 kGs and magneto-crystalline anisotropy constant of −1.88 × 106 erg/cm3. • The ultrahigh natural resonance frequency of 4.1 GHz in Y 2 Co 17 thin-film is obtained. Y 2 Co 17 thin films grown along the c axis with planar anisotropy were fabricated by magnetron sputtering and annealed by vacuum heat treatment with rapid water-cooling technologies. The results demonstrate that the annealing temperature had a significant impact on structures and morphologies of the films. The phase structure transformed from rich fcc-Co phase to Y 2 Co 17 intermetallic compounds with the increasing annealing temperature. The Y 2 Co 17 thin film annealed at 600 °C has a saturation magnetization of around 13.5 kGs and a negative magneto-crystalline anisotropy constant of −1.88 × 106 erg/cm3, respectively. The high-frequency performance of the film show that, in the absence of an induced in-plane anisotropy field, the zero-field natural resonance frequency exceeds 4 GHz. [ABSTRACT FROM AUTHOR]

The phase structure transformed from rich fcc-Co phase to Y 2 Co 17 intermetallic compounds with the increasing annealing temperature. The Y 2 Co 17 thin film annealed at 600 °C has a saturation magnetization of around 13.5 kGs and a negative magneto-crystalline anisotropy constant of −1.88 × 106 erg/cm3, respectively.
