Abstract

Using a method of in-situ pressing X-ray diffraction, a uniaxial pressure-induced unusual change of lattice parameters and a remarkable crystal structural distortion have been observed in the perovskite-type La-Sr-Mn-O system. The pressure coefficient of lattice parameter in [200] orientation, i.e. dlnd_Mn-O-Mn/dP, can reach about 3.76 × 10^-4/Map for La_0.85Sr_0.15MnO₃. Under a uniaxial pressure of only 20∼30 MPa, a giant piezoresistance and an evident increase of Tp, the onset of the metal-semiconductor-like (M-S) transition have also been obtained. These effects suggest that the structure of colossal magnetoresistance perovskites is very flexible and their transport properties are structurally sensitive.
