Abstract

Optical reflectivity studies of the ferromagnetic metal (FMM) to anti ferromagnetic insulator (AFI) phase transition were performed on Nd0.5Sr0.5MnO3 single crystals in a wide temperature and magnetic field range. The formation of a domain structure in the AFI state was observed. On the basis of the experimental results and symmetry analysis we conclude that these domains are crystal twins, confirming the symmetry lowering of the crystal at this phase transition. The twin domain structure of the AFI state in the Nd0.5Sr0.5MnO3 is visible in reflected unpolarized light due to a different tilting of the surface of the domains. We find no evidence for intermediate FMM + AFI stripe phase. (C) 2002 Elsevier Science B.V. All rights reserved.
