[en] Pr 1-x Ba x MnO 3 (0< x< 0.40) perovskites form at room temperature two different
orthorhombic phases: the first one (x< 0.20; Pbnm symmetry) shows a double tilting of the …

The structural and magnetic transitions in the Pr0. 5Sr0. 5-x Ba x MnO3 series have been
investigated by neutron diffraction and electron microscopy, in connection with the transport …

The exploration of the Mn4+-rich side of the Pr1-x Sr x MnO3 system has allowed the
extension of the domain of the cubic perovskite, by using a two-step process, combining …

The mixed-valence manganites Pr1− xKxMnO3have been prepared up to maximum content
of 30% Mn4+ (x= 0.15 in the ideal case) and investigated by the neutron diffraction and …

A comprehensive account of structural features in mixed Mn 3+, Mn 4+ perovskites, Pr 1− x A
