Size dependence of Peltier cooling in ferromagnet/Au nanopillars

We study Peltier cooling in current-perpendicular-to-plane multilayer nanopillars with diameters D varying from 60 to 430 nm and made from Au and various ferromagnets (FMs): Heusler compounds Co2MnSi and Co2FeSi (CFS) and conventional FM metals Fe and Co. We report an enhanced effective Peltier coef...
