Resumen:
High-temperature powder X-ray diffraction and magnetization measurements were performed on LaMnO3.o0 fromroom temperature up to 600°C. X-ray diffraction data show a transition from a distorted orthorhombic phase toa pseudocubic one. These two phases coexist within 350 < T < 450°C. This result was confirmed through hightemperaturemagnetization measurements where a hysteretic behavior of the susceptibility was observed in this range oftemperature.
