Paramagnetic spins take electrons for a ride, produce electricity from heat

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,' converts a temperature difference into an electrical voltage.
