摘要
presented for electron microrefrigeration based on ferromagnet-superconductor contacts. In this setup, cooling power densities up to 600 nW/μm2 can be achieved leading to electronic temperature reductions largely exceeding those obtained with existing superconductor-normal metal tunnel contacts. Half-metallic CrO2/Al bilayers are indicated as ideal candidates for the implementation of the device.
