Pressure-induced structural transformations, orbital order and antiferromagnetism in La0.75Ca0.25MnO3.
Original language description
High pressure evolution of structural, vibrational and magnetic properties of La0.75Ca0.25MnO3 was studied by means of X-ray diffraction and Raman spectroscopy up to 39 GPa, and neutron diffraction up to 7.5 GPa. The stability of different magnetic ground states, orbital configurations and structural modifications were investigated by LDA + U electronic structure calculations. A change of octahedral tilts corresponding to the transformation of orthorhombic crystal structure from the Pnma symmetry totheImma one occurs above P6 GPa. At the same time, the evolution of the orthorhombic lattice distortion evidences an appearance of the eg dx2-z2orbital polarization at high pressures.
