Abstract
Two ferroelectric YMn2O5 samples with different phases were prepared, one is orthorhombic (OR) and another is hexagonal (HX) structure, for investigating the structure dependency of magnetic properties. The crystal structures and magnetic properties of the samples were examined by X-ray diffraction (XRD) and physical property measurement system, respectively. Based on the results of temperature-dependent magnetization and low temperature magnetic hysteresis curves, the two samples display a spin glass/spin-canted state at low temperature and the hexagonal sample is more ferromagnetic than that of orthorhombic structure.
