Abstract

The magnetic and the transport properties of a 20-nrn-scale twinned La_0.65Ca_0.35MnO₃ film have been investigated in a temperature range of 77 - 300 K. The coexistence of ferromagnetic metallic and charge-ordered insulating phases is suggested by the temperature and the current dependences of the resistance at low temperatures. It is shown that thermocycling leads to the formation of a nonequilibrium state in the ensemble of charge-ordered domains and to the appearance of a giant switching in resistance up to 100%. The experimental results are discussed on the basis of phase separation.
