Thermoelectric effects can be used to convert waste heat into electricity. One particularly promising thermoelectric mechanism is the spin Seebeck effect as the transverse geometry is ideal for device integration, even if currently it lacks sufficient thermoelectric conversion efficiency. Here, Kim et al, tackle this limitation, showing that oxidizing the ferromagnet layer used in the spin Seebeck effect can significantly enhance the thermoelectric efficiency.
