Abstract
We investigated the magnetoresistance of La2/3Ca1/3MnO3+delta magnetic thin films. Under certain conditions, the magnetoresistance curves sh ow a remarkable hysteresis and the resistance becomes dependent on the magnetic history. A relaxation behavior of the resistance has also be en observed. Hysteresis and relaxation of the resistance are very simi lar to the phenomena of magnetoviscosity of the magnetic moment in spi n glasses and the magnetic aftereffect in hard magnets.
