- W4256094788 abstract "We present a detailed magnetic and structural study of Bi0.75Sr0.25MnO3. With the aid of electron diffraction, neutron and synchrotron powder diffraction measurements we have found that at ∼600K the structure presents a considerable distortion of the cell parameters accompanied by a change in the space group and by the appearance of a modulation of the average structure. This modulation doubles the a and c lattice parameters (in the P bnm setting) of the high-temperature structure. Magnetic data reveal below this temperature that the paramagnetic units are not single Mn ions but a coexistence of Mn3+ and Mn–Mn pairs. This behavior strongly contrasts with that of Bi0.75Ca0.25MnO3 evidencing the strong differences between the Bi1−xSrxMnO3 and Bi1−xCaxMnO3 families." @default.
