摘要： A magneto-resistive element employs a CPP structure and includes an antiferromagnetic layer, a pinned magnetization layer, a nonmagnetic intermediate layer and a free magnetization layer that are successively stacked. The pinned magnetization layer includes a first pinned magnetization layer, a nonmagnetic coupling layer and a second pinned magnetization layer that are successively stacked on the antiferromagnetic layer. The first and second pinned magnetization layers are antiferromagnetically exchange-coupled. The first pinned magnetization layer includes a resistance control layer made of a ferromagnetic material that is added with an additive element.

摘要： A device that estimates a positional relationship between loads individually connected through sensors to electric power-supply ends provided in a power distribution network includes a communication unit configured to change a resistance value located between each of electric power-supply ends and a ground terminal of each of sensors and measure a voltage value produced between each of the electric power-supply ends and the ground terminal; and a determination unit configured to acquire voltage values from the two selected sensors from among the sensors after a resistance value of one of the two sensors that has a higher acquired voltage value is changed, calculate a ratio between voltage values acquired before and after the resistance value is changed, and determine that the two sensors are connected to a branch circuit in a same system in the power distribution network, when each ratio about the two sensors is within a specified range.

摘要： A spin valve film has a lamination structure of a pinned layer, a non-magnetic intermediate layer and a free layer. The pinned layer is made of ferromagnetic material and has a fixed magnetization direction. The non-magnetic intermediate layer is made of non-magnetic conductive material. The free layer is made of ferromagnetic material and changes a magnetization direction by external magnetic field. Electrodes let current flow through the spin valve film in a lamination direction. At least one of the pinned layer and the free layer includes a lamination portion of a first layer and a second layer stacked alternately. The first layer has a composition ratio of elements presenting ferromagnetism higher than that in the second layer. The second layer has a composition ratio of elements presenting non-magnetism higher than that in the first layer. The lamination portion includes at least two first layers and at least one second layer.
