Claim:
1. A magnetoresistive structure, comprising: a first magnetic layer having a fixed magnetization direction, the first magnetic layer including an upper surface, a lower surface and side surfaces perpendicular to the upper surface and the lower surface; a second magnetic layer operatively connected to the first magnetic layer, the second magnetic layer having a changeable magnetization direction; and a magnetoresistance (MR) enhancing layer and an intermediate layer both between the first magnetic layer and the second magnetic layer, wherein a first portion of the MR enhancing layer surrounds the upper surface and the side surfaces of the first magnetic layer, an inner surface of the intermediate layer has a profile conformal to a profile of the first portion of the MR enhancing layer, and the second magnetic layer is operatively connected to the intermediate layer such that a total surface area of the second magnetic layer is larger than a total surface area of the first magnetic layer.
