Growth, transport, and magnetic properties of Pr0.67Ca0.33MnO3 thin films

By S. K. Singh, Stuart B. Palmer, Don McK. Paul and Martin R. Lees


We have grown Pr0.67Ca0.33MnO3 thin films on LaAlO3 using pulsed laser deposition. Below 50 K, a field induced insulator-metal transition results in changes in resistivity of at least 6 orders of magnitude. The field induced conducting state is metastable at low temperature. The temperature dependence of the resistivity exhibits considerable hysteresis in a field of 40 kOe but becomes reversible in a field of 80 kOe
