Abstract

A magnetoresistive element has two magnetic layers and a nonmagnetic middle layer having organic molecules disposed between the two magnetic layers. The middle layer is thinner than 5 nm (50 Å). The magnetoresistive element exhibits a magnetoresistive effect as a function of the relative alignment of magnetizations of the first and the second magnetic layers and can be used in a magnetoresistive sensor in the based on GMR or TMR.
