摘要：

Magnetization and resistivity measurements are reported fur a series of radiation damaged La0.7Ca0.3MnO3 pulsed laser deposited thin films. When plotted as a function of activation energy, trends in the electrical transport properties are similar to those exhibited in the magnetic properties. A sharp drop in both T-c and T-p in samples with activation energies greater than similar to 110 meV suggests a "decoupling" of the magnetic and transport properties. The results suggest the magnetic order is no longer sufficient to delocalize the system of the extra disorder induced by the radiation damage. [S0021-8979(98)38011-1].
