  The transverse thermoelectric effect refers to the conversion of a
temperature gradient into a transverse charge current, or vice versa, which
appears in a conductor under a magnetic field or in a magnetic material with
spontaneous magnetization. Among such phenomena, the anomalous Nernst effect in
magnetic materials has been receiving increased attention from the viewpoints
of fundamental physics and thermoelectric applications owing to the rapid
development of spin caloritronics and topological materials science. In this
research trend, a conceptually different transverse thermoelectric conversion
phenomenon appearing in thermoelectric/magnetic hybrid materials has been
demonstrated, enabling the generation of a large transverse thermopower. Here,
we review the recent progress in fundamental and applied studies on the
transverse thermoelectric generation using magnetic materials. We anticipate
that this perspective will further stimulate research activities on the
transverse thermoelectric generation and lead to the development of
next-generation thermal energy harvesting and heat-flux sensing technologies.
