摘要：

Static-spray deposition of a polyol-based sol, containing nanoparticles of NiZn ferrite, on a moderately heated glass support, has been used to generate crystalline thin films. The films exhibit superparamagnetic behavior with a blocking temperature, which decreases as the zinc content increases, due to their nanocrystalline character. At low temperature, the films are ferrimagnetic; the saturation magnetization and the coercivity depend markedly on both the zinc content and the microstructure.
