Abstract: A magnetoresistive sensing component includes a strip of horizontal magnetoresistive layer, a conductive part and a first magnetic-field-sensing layer. The strip of horizontal magnetoresistive layer is disposed above a surface of a substrate and has a first side and a second side opposite the first side along its extending direction. The conductive part is disposed above or below the horizontal magnetoresistive layer and electrically coupled to the horizontal magnetoresistive layer. The conductive part and the horizontal magnetoresistive layer together form at least an electrical current path. The first magnetic-field-sensing layer is not parallel to the surface of the substrate and magnetically coupled to the horizontal magnetoresistive layer at the first side of the horizontal magnetoresistive layer.
