Non-linear conductivity behavior at low temperatures
Abstract
A current-controlled negative differential resistance has been revealed in the I-V characteristics of single crystal LaCuO in the low temperature region. The non-linear behavior of conductivity is accompanied by a transition from positive to negative magnetoresistance when the current is growing. Possible reasons for the effect observed are discussed.
