Abstract: Sm3+-Cu2+ was simultaneously introduced to tune the magnetocrystalline anisotropy field (H a) of BaFe 12 O 19 (BaM) while maintaining the valence equilibrium for the application for the self-biased circulators, Ba 1-x Sm x Fe 12-x Cu x O 19 was fabricated via solid-state reaction combined with magnetic field orientation. As x = 0.1, purity M phase, most homogeneous grain size, high remanence ratio (86%), suitable magnetocrystalline anisotropy field (8143 Oe), relatively lowest porosity was realized, the ferromagnetic resonance linewidth was test by perturbation method on U-band (800 Oe, 55 GHz). The magnetic force microscopy (MFM) verified the sample belong to quasi single magnetic domain. The above properties suggested this sample have potential for the application of self-biased circulators. [ABSTRACT FROM AUTHOR]
