The tetragonal–orthorhombic transition and the associated changes in the properties of Pr0.5−xNdxSr0.5MnO3

The transition from the tetragonal (I4/mcm) to the orthorhombic (Imma) structure associated with a change in A- to CE-type antiferromagnetism in the Pr0.5−x Nd x Sr0.5MnO3 has been investigated by X-ray diffraction as well as magnetization and resistivity measurements. The transition is found to occur between x=0.1 and 0.2.
