Abstract
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.
