摘要：

Zr-substituted NiZn ferrite thin films, Ni0.5Zn0.5ZrxFe2-xO4 (0 <= x <= 0.2), were synthesized by sol-gel process. The structure and magnetic properties of Ni0.5Zn0.5ZrxFe2-xO4 ferrite thin films have been investigated. The diffraction peak shifted towards the lower angle and the lattice parameter increased with Zr substitution. The average grain size of Zr-substituted NiZn ferrtie thin films increased with Zr substitution. The saturation magnetization gradually increased with the increase of Zr substitution when x <= 0.10, and decreased when x > 0.10. Meanwhile, the coercivity initially decreased with the increase of Zr substitution when x <= 0.10, and increased when x > 0.10. (c) 2012 Elsevier B.V. All rights reserved.
