Abstract

Conductivity of current-biased La_0.82 Ca_0.18 MnO ₃ low-doped manganite single crystals has been investigated in wide temperature and magnetic field ranges. Strong zero-bias anomalies in the form of conductance minima and maxima have been observed below the Curie temperature T_C. Applied magnetic field and temperature strongly affect the anomaly and cause its transition from the conductance minimum to the conductance maximum. The observed anomalies are ascribed to Anderson localisation and combined Kondo and Fano effects.
