Ken-ichi Uchida (Distinguished Group Leader), Takamasa Hirai (Researcher), Fuyuki Ando (Special Researcher), and Hossein Sepehri-Amin (Group Leader) have demonstrated that the transverse thermoelectric conversion (i.e., energy conversion between charge and heat currents that flow orthogonally to each other) can be greatly enhanced by applying magnetic fields or utilizing magnetism. In addition, the team developed a thermoelectric permanent magnet—a new functional material capable of thermoelectric cooling and power generation—by combining permanent magnets and thermoelectric materials into a hybrid structure. These results may guide in achieving thermal management and energy harvesting using common magnets.
