For the first time in the world, a research team led by Dr. Hirai and Dr. K. Uchida has successfully observed the transverse Thomson effect—a phenomenon in which metals or semiconductors release or absorb heat when a heat current, charge current and magnetic field are applied orthogonally to each other.

For the first time in the world, a research team led by Dr. Hirai (Senior Researcher) and Dr. K. Uchida (Distinguished Group Leader) has successfully observed the transverse Thomson effect—a phenomenon in which metals or semiconductors release or absorb heat when a heat current, charge current and magnetic field are applied orthogonally to each other. This achievement may contribute to advances in physics and materials science related to the conversion between heat, electricity and magnetism, as well as to the development of new thermal management technologies.
