Abstract
A magnetoresistive element comprising a combination of an electroconductive, crystalline magnetostrictive material or an amorphous magnetostrictive material with an electrically insulating layer and an oxide magnetoresistive material, or a combination of an electrically insulating oxide magnetostrictive material with an oxide magnetoresistive material. The magnetoresistive element provides a magnetic detecting element, detector or recording device having high sensitivity and good quick response by virtue of synergistic effect of the large magnetostriction and the magnetoresistance effect thereof. The oxide magnetoresistive material is preferably an oxide having a perovskite structure or a layer perovskite structure and the preferred magnetostrictive material is a crystalline or amorphous ferromagnetic material. The electrically insulating layer is formed of preferably an oxide having a perovskite structure.
