Abstract:
A magnetoresistive device comprising:a high-resistivity layer, a first magnetic layer and a second magnetic layer, the first magnetic layer and the second magnetic layer being arranged so as to sandwich the high resistivity layer, wherein: a first side of the high-resistivity layer is in contact with the first magnetic layer, and a second side of the high-resistivity layer is in contact with the second magnetic layer; the high-resistivity layer is a barrier for passing tunneling electrons between the first magnetic layer and the second magnetic layer, and contains at least one element LONC selected from oxygen, nitrogen and carbon; at least one layer A selected from the first magnetic layer and the second magnetic layer contains at least one metal element M selected from Fe, Ni and Co, and an element RCP different from the metal element M; and the element RCP combines with the element LONC more easily in terms of energy than the metal element M combines with the element LONC.
