| 中文摘要 | The observation of giant magnetoresistance (GMR) effect in sputtered Fe/Ag multilayers is presented. The observed maximum GMR amounts to -7.3% at 1.5 K. The amplitude of the GMR oscillates with variation of Ag thickness, and the oscillation period is about 11 Angstrom. The origin of the GMR in these Fe/Ag multilayers is believed to lie mainly in the interface. The GMR effect contains contributions either arising from the antiferromagnetic coupled magnetization in the neighboring Fe layer or superparamagneticlike spins at the interface. An anomalous temperature dependence of magnetoresistance is reported and it is attributed to the suppression of thermal excitations of superparamagneticlike spins by applied magnetic field, which results in a reduction of the GMR effect with decreasing temperature. In addition, the specific field dependence of the magetoresistance curve with respect to temperature is also accounted for by the contribution from those arising from superparamagneticlike spins at the interface, which could be easily quenched at low temperature, leading to the observation of a decreasing tendency of saturation field with decreasing temperature. |
