During the study of magnetoresistivity in La(1-x)Ca(x)MnO(3) it was found that after cycling of the magnetic field, some kind of magnetic field memory effect was observed. For La0.5Ca0.5MnO3 after cycling of the magnetic field to 13T and back to zero,"frozen"magnetoresistivity decreases about 20 times comparing to zero field value, while for La(0.47)Ca(0.53)MnO(3) it is already about four orders of magnitude. This effect can be observed only for concentration region 0.45<x<0.55. In zero…
