Abstract

Single crystals of Zr-substituted Zn-Y (Zr-ZnY; Ba₂Zn ₂Zr_xFe_12-xO₂₂) were grown from the flux system of BaCO₃ and B₂O₃ by a high temperature slow cooling flux method. X-ray diffraction pattern confirmed the crystal structure with Zn-Y composition. The single crystals were characterized for magnetic and microwave properties. The measured anisotropy field (H_A) and the in-plane magnetization (σ_s) are 13 kOe and 52.0 emu/g, respectively. Ferrimagnetic resonance measurements show 18 Oe of linewidth (δH) at 9 GHz. The combination of low δH with a high δH_A in Zr-ZnY hexaferrite is suitable for microwave devices, which can operate with low external biasing field.
