摘要： In a spin-torque oscillator, a first ferromagnetic layer, a non-magnetic layer and a second ferromagnetic layer are stacked. A pair of electrodes perpendicularly applies a current onto each plane of the first ferromagnetic layer, the non-magnetic layer and the second ferromagnetic layer. The current induces a precession of a magnetization of at least one of the first ferromagnetic layer and the second ferromagnetic layer. The at least one is formed by an in-plane magnetization film having a uniaxial magnetic anisotropy. A magnetic field generator generates a magnetic field to control a direction of the magnetization so that a non-linearity frequency shift of the precession by the uniaxial magnetic anisotropy cancels a non-linearity frequency shift of the precession by a demagnetizing field on the in-plane magnetization film.

One of the spin tunnel transistor comprises a collector; an emitter; abase formed between the collector and the emitter, including a first ferromagnetic metal layer variable in its magnetization under an external magnetic field; a barrier layer formed between the first ferromagnetic metal layer and one of the collector and the emitter, the other of the collector and the emitter including a semiconductor crystal layer; and a transition metal silicide crystal layer between the semiconductor crystal layer and the base. The transition metal silicide crystal layer may be replaced with a palladium layer, a transition metal nitride layer, or a transition metal carbide layer.

摘要： A magnetic sensor has a three-terminal magnetic device consisting of an emitter, a base, and a collector. A semiconductor layer serving as the collector and a magnetic multilayered film serving as the base form a Schottky junction. The magnetic multilayered film has two magnetic films opposing each other with a nonmagnetic film between them. The emitter constructed of a metal film and the base are connected via a tunnel insulating film. The relationship between the magnetization directions in the magnetic films changes in accordance with an external magnetic field, and this changes the value of a current flowing through the magnetic device. The external magnetic field is sensed on the basis of this change in the current value.
