The Role of Impurity States in Garnet Magnetic Semiconductor Films

摘要

The experiments of the electrical conductivity on the different frequencies and magnetoresistance effect were performed on Si- substituted Y_3Fe_5O_(12) films. Nonlinear V-I― characteristics wereobserved. Effects of impurity states Si~(4+) + (Fe~(3+) <-> Fe~(2+)) on the magnetic and electrical properties of garnet magnetic semiconductors are analyzed.
