Abstract

The list of materials systems displaying both electric and magnetic long range order is short. Oxides, however, concentrate numerous examples of multiferroicity with, in some cases, a large magnetoelectric coupling. As a result, a fruitful research field has emerged contemporaneously with the consolidation of spintronic. The synergy between multiferroics and spintronics was meant to be inevitable and hence the characterization of spintronic functionalities in multiferroic materials is rather abundant. The aim of the present chapter is to review the oxide heterostructures where magnetoelectric coupling is demonstrated by means of spintronic functionalities (i.e. magnetoresistance, anisotropic magnetoresistance, giant magnetoresistance or tunnel magnetoresistance).
