ABSTRACT:
A magnetoresistive sensor element has a first magnetic layer structure, a second magnetic layer structure, and a barrier layer. The resistance R1of the first magnetic layer structure, the resistance R2of the second magnetic layer structure and resistance-area product RA define a characteristic length λ of the magnetoresistive sensor element by a functional relation. The contact spacing X0has an m-fold value of the characteristic length λ with 0.1<m<20, the first contact terminal a first edge spacing X1from the edge of the first magnetic layer structure with an n-fold value of the characteristic length λ with 0.5<n, the second contact terminal a second edge spacing X2from the edge of the first magnetic layer structure with a p-fold value of the characteristic length λ with 0.5<p, the resistance R1a q-fold value of the resistance R2with q>1.
