论文摘要
已经在高温范围内研究了SMCO $ _5 $ -Type永久磁铁中的异常Ettingshausen效应（AEE）。从室温到约600 k的高温范围。Smco$ _5 $ _5 $和（SMGD）CO $ _5 $ _5 $ _5 $ _5 $ notofity的温度相似的eTtingshausen系数在SMCO $ _5 $ _5 $ _5 $ _5 $ _5 $ _5 $ _5 $ _5 $ _5 $ type（AEE）。 SMCO $ _5 $略大于高温下（SMGD）Co $ _5 $的SMCO $。高温下SMCO $ _5 $中AEE的无量音数字比以前获得异常效果的记录要大得多。根据横向转运系数的第一原理计算，讨论了观察到的AEE的高温行为。
The anomalous Ettingshausen effect (AEE) in SmCo$_5$-type permanent magnets has been investigated in the high-temperature range from room temperature to around 600 K. The anomalous Ettingshausen coefficient of the SmCo$_5$ and (SmGd)Co$_5$ magnets monotonically increases with increasing the temperature and shows the similar temperature dependence, while the coefficient of SmCo$_5$ is slightly larger than that of (SmGd)Co$_5$ at high temperatures. The dimensionless figure of merit for AEE in SmCo$_5$ at high temperatures is much greater than the previous record obtained for the anomalous Nernst effect. The observed high-temperature behavior of AEE is discussed based on the first-principles calculations of transverse transport coefficients.
