Abstract

Pronounced noise signatures enabling one to discriminate metastable resistivity states in La_0.86Ca_0.14MnO₃ single crystals have been observed. The normalized noise spectra for metastable resisitivity differ both in shape and magnitude, indicating that the metastable state is associated with transition of the electronic system into another local minimum of the potential landscape. Such scenario is consistent with freezing of the electronic system into a Coulomb glass state.
