X-ray Diffraction Investigation in High Fields at Low Temperature for Nd0.5Sr0.5MnO3
A phase transition induced by a magnetic field in Nd0.5Sr0.5MnO3 was investigated using a newly developed high field low temperature X-ray diffraction system. A cryocooled split-pair superconducting magnet was combined with a powder X-ray diffraction apparatus. The change of lattice parameters in Nd0.5Sr0.5MnO3 was directly obtained in fields up to 5 T and at temperatures from 200 K to 8.9 K. It is found that the structure in Nd0.5Sr0.5MnO3 changes from the orthorhombic Ibmm space group at 0 T and 300 K to the orthorhombic Pbnm space group at 5 T and 8.9 K.
