Lattice crossover and phase transitions in NdAlO3–GdAlO3 system

Phase and structural behaviour in the (1−x)NdAlO3–xGdAlO3 system in a whole concentration range has been studied by means of in situ high-resolution X-ray synchrotron powder diffraction technique and differential thermal analysis. Two kinds of solid solutions Nd1−xGdxAlO3 have been found at room tem...
