Abstract

See full text

The magnetoresistive element includes a semiconductor channel layer, a pinned layer disposed on the semiconductor channel layer via a first tunnel layer, a free layer disposed on the semiconductor channel layer via a second tunnel layer, wherein the semiconductor channel layer includes a first region containing an interface with the first tunnel layer, a second region containing an interface with the second tunnel layer, and a third region, impurity concentrations in the first and second regions are higher than 1×1019 cm−3, an impurity concentration in the third region is 1×1019 cm−3 or less, the first and second regions are separated by the third region, and the impurity concentrations in the first and second regions decrease in the thickness direction of the semiconductor channel layer from the interface between the semiconductor channel layer and the first tunnel layer and the interface between the semiconductor channel layer and the second tunnel layer.
