Abstract
By utilizing three kinds of incident X-ray radiation under the magnetic fields of 0 T and 5 T, the coexistent region of high-temperature ferromagnetic and low-temperature anti-ferromagnetic phases for the titled manganite oxide was investigated with temperature change between 300 K and 10 K. The unusual extension of the two-phase coexistent region to lower temperature was observed with cooling under 5 T for CuKα radiation, and was estimated due to a surface effect. The large amount of the remnant high-temperature ferromagnetic phase observed in the previous investigations for powder sample under magnetic field was considered by this effect.
