Optical reflectivity studies of the ferromagnetic metal (FMM) to antiferromagnetic insulator (AFI) phase transition are performed on Nd₀.₅Sr₀.₅MnO₃ manganite in a wide temperature and magnetic field range. The formation ...

The crystal structure of the manganite Nd₀.₅Sr₀.₅MnO₃ is studied at temperatures 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 ...
