A new way to generate electricity from waste heat: Using an antiferromagnet for solid devices
Forcing electrons to flow perpendicularly to a heat flow requires an external magnetic field—this is known as the Nernst effect. In a permanently magnetized material (a ferromagnet), an anomalous Nernst effect (ANE) exists that can generate electri.....»»
