The invention relates to a magnetic sensor and a magnetic memory which sense magnetic information held by a ferromagnetic body without a current flowing through the ferromagnetic body. The magnetic sensor and magnetic memory use a magnetoresistive effect generated in a current that flows through a metal layer along an interface, on at least the interface side, with a ferromagnetic dielectric layer and said metal layer being joined through said interface.

Magnetic sensor and magnetic memory

The thermoelectric conversion efficiency of a thermoelectric conversion device is increased by increasing the figure of merit of a spin-Seebeck effect element. An inverse spin-Hall effect material is provided to at least one end of a thermal spin-wave spin current generating material made of a magnetic dielectric material so that a thermal spin-wave spin current is converted to generate a voltage in the above described inverse spin-Hall effect material when there is a temperature gradient in the above described thermal spin-wave spin current generating material and a magnetic field is applied using a magnetic field applying means.
