摘要
High-temperature powder X-ray diffraction and magnetization measurements were performed on LaMnO3.00 from room temperature up to 600 degrees C. X-ray diffraction data show a transition from a distorted orthorhombic phase to a pseudocubic one. These two phases coexist within 350 < T < 450 degrees C. This result was confirmed through high-temperature magnetization measurements where a hysteretic behavior of the susceptibility was observed in this range of temperature.
