【摘要】 针对用磁控溅射方法制备的NiFe/Cu多层膜进行了热处理研究。经退火后,NiFe/Cu多层膜的磁电阻有了显著的变化,在250℃的最佳退火温度下,最大磁电阻变化率为5.2％。更多还原

【Abstract】 The magnetoresistive (MR) properties of sputtered NiFe/Cu multilayers (MLs) have been investigated as a function of thermal treatments. The MR of the NiFe/Cu MLs were improved with annealing treatments. Annealing at 250℃ results in a maximum MR ratio of up to 5.2％. In addition, the MR-H curves are found to be perfectly linear and reversible.更多还原
