Paramagnetic spins take electrons for a ride, produce electricity from heat
An international team of researchers has observed that local thermal perturbations of spins in a solid can convert heat to energy even in a paramagnetic material—where spins weren't thought to correlate long enough to do so. This effect, which the researchers call "paramagnon drag thermopower,"...
