Description 638-642
The structure and magnetic properties of perovskite chromium oxide YCrO3 and its doping system are systematically
studied. Ceramic samples are prepared by solid state method. X-ray diffraction patterns reveal that the materials are
orthorhombic structure with space group Pnma. The result of magnetic study of YCrO3 and the doping system show that the
antiferromagnetism and ferromagnetism coexist in the system. The magnetism comes from the exchange interactions
between Cr ions. The results of magnetothermal curve reveal that all the samples show the negative magnetization induced
by temperature and doping at different positions affects the compensation temperature, which is related to the interaction of
magnetic ions in the system. The doping of Ce ions in Y-position affects the coercivity of hysteresis loop, but it has no effect
on the magnitude of magnetization. While, the doping of Fe ions enhances the antiferromagnetism of the system and makes
the magnetization decrease obviously. The phenomenon of negative magnetization in the sample makes it possible for this
kind of material to be used in magnetic sensor parts.
