Domain structure of the antiferromagnetic insulating state in Nd₀.₅Sr₀.₅MnO₃
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 of a domain structure in the AFI state during the FMM−AFI phase transition is ob...
