【Abstract】 Metal/semiconductor Fe/In 2O 3 granular films were successfully prepared by the radio frequency sputtering. The magnetic behavior of the samples undergoes a special anti ferromagnetism like magnetic transition from superparamagnetism to the coexistence of ferromagnetism and superparamagnetism. As a result, we propose that there exist Fe particles of two different sizes in Fe/In 2O 3.更多还原
