The hysteresis curves of multilayer microwires consisting of a soft magnetic nucleus,
intermediate nonmagnetic layers, and an external hard magnetic layer are investigated. The
magnetostatic interaction between magnetic layers is proved to give rise to an
antiferromagneticlike coupling resulting in a magnetostatic bias in the hysteresis curves of
the soft nucleus. This magnetostatic biasing effect is investigated in terms of the microwire
geometry. The experimental results are interpreted considering an analytical model taking …
