Investigation of InSb:Mn thin films magnetoresistance by I-V characteristics method

We have investigated the effect of magnetoresistance in the thin films of InSb:Mn using the data of I-V curves. The thin films were produced by pulsed laser deposition (PLD) method from the InSb+MnSb composite alloy targets with the concentrations of MnSb to 20%. The temperature dependence of magnetoresistance of the films has been studied in the temperature range from 10K to 300K.
