Abstract: The invention provides a magnetoresistance element with a configuration such that a stable switching action is possible with a current flowing in response to the application of a unipolar electrical pulse, and a non-volatile semiconductor storage device using the magnetoresistance element. A magnetoresistance element 1-1 includes a magnetic tunnel junction portion 13 configured by sequentially stacking a perpendicularly magnetized first magnetic body 22, an insulation layer 21, and a perpendicularly magnetized second magnetic body 200. The second magnetic body 200 has a configuration wherein a ferromagnetic layer and a rare earth-transition metal alloy layer are stacked sequentially from the insulation layer 21 side interface.

Abstract: A non-contact current sensor includes a spin valve structure (2), an electrical unit (4) that applies a varying current to the spin valve structure (2), and a resistance reading unit that electrically reads out a resistance value of the spin valve structure (2). When a current-induced magnetic field is detected, a coercive force of a free layer (14) is configured to be larger than the current-induced magnetic field as a detection target, and the electrical unit (4) allows the magnetization directions of a pinned layer (12) and the free layer (14) to transition between a mutually parallel state and a mutually anti-parallel state by applying the current to the spin valve structure (2). The resistance reading unit (5) detects a threshold value corresponding to the transition.

Abstract: A spin valve element may include a plurality of magnetic element groups. Each magnetic element group may be formed, at least in part, by a plurality of magnetic elements being connected in parallel. Each magnetic element may include an intermediate layer and a pair of ferromagnetic layers sandwiching the intermediate layer. The plurality of magnetic element groups may be connected together in series or in parallel. The plurality of magnetic elements may be configured to undergo a microwave oscillation and are placed in proximity sufficient that oscillation signals are configured to be generated with the magnetic elements mutually synchronized. The proximity may include a range equal to a wavelength of the microwave oscillation.

Abstract: In order to increase the power which can be passed to a spin valve element, an insulating layer 24 or a nonmagnetic layer 51 is sandwiched by ferromagnetic layers 23, 25, and a porous layer 10(10?) having a plurality of minute holes is placed so as to be in contact with one of the ferromagnetic layers, or near the ferromagnetic layer with another layer intervening. By this means, even when a single-domain magnetic multilayer film extending over a broad region is not used, when, for example, microwave oscillation is induced by means of the spin valve element, the microwave power can be increased.
