Single crystals of Zr-substituted Zn-Y (Zr-ZnY; Ba2Zn 2ZrxFe12-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 (HA) and the in-plane magnetization (σs) 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 δHA in Zr-ZnY hexaferrite is suitable for microwave devices, which can operate with low external biasing field.
