本文对磁性多层膜的磁热效应进行了实验研究。提出了一种新的测量技术，用于精确测量Co/Cu磁性多层膜的磁热导率及其与磁电阻的关系。测量技术涉及一个悬浮图案化的磁性薄膜带使用光刻技术，以创建一个理想的一维热流。3ω方法已被采用沿着与其他开发的技术，以获得准确的磁热导率测量。结果表明，在外加磁场作用下，磁热导率与磁电导率之间存在较好的相关性，但两者的变化幅度较大。
In this paper, we present an experimental study on magneto-thermal effect in magnetic multilayers. A novel measurement technique has been developed and employed to obtain accurate measurements of magneto-thermal conductance and correlations with magnetoresistance in Co/Cu magnetic multilayers. The measurement technique involves a suspending patterned magnetic film strip using lithography technique to create an ideal one-dimension heat flow. 3ω method has been employed along with additional developed techniques to obtain accurate magneto-thermal conductivity measurements. It is found that the magneto-thermal conductance correlates well with the magneto-electric conductance under the application of magnetic field, however, with significant greater percentage change.
