X-ray study of Nd0.5Sr0.5MnO3 manganite structure above and below the ferromagnetic metal-antiferromagnetic insulator spontaneous phase transition
UNSPECIFIED. (2001) X-ray study of Nd0.5Sr0.5MnO3 manganite structure above and below the ferromagnetic metal-antiferromagnetic insulator spontaneous phase transition. LOW TEMPERATURE PHYSICS, 27 (11). pp. 930-934. ISSN 1063-777XFull text not available from this repository.
The crystal structure of the manganite Nd0.5Sr0.5MnO3 is studied at temperature T=300 and 77.3 K by means of an x-ray diffractometer. It is shown that the transition from the ferromagnetic metallic state to the antiferromagnetic insulating charge-ordered state is accompanied by a lowering of the symmetry of the structure from orthorhombic to monoclinic. The space-group symmetry of the orthorhombic and monoclinic phases is identified as Imma and P2(1)/m, respectively. Twinning of the crystal and the formation of a twin domain structure with coherent boundaries in the (00l) crystallographic planes are found. (C) 2001 American Institute of Physics.
