Abstract
This invention relates to a multilayered magnetic structure comprising an alternate stack of: PA1 layers (6, 16) of a first type based on magnetic materials, PA1 layers (12) of a second type, made of Ag or an Ag rich alloy, PA1 a thin interface layer (8, 14) of Co or a Co rich alloy being located at the interface between layers of the first type and layers of the second type. The invention also relates to a process for making this type of structure. Applications to sensors based on magnetoresistive effects, such as current sensors or magnetic heads.
