Abstract

We have studied the magnetic stability in exchange-bias and exchange-spring systems during repeated reversal of the pinned layer. The samples were prepared by epitaxial sputter deposition. The exchange-biased system consists of a combination of ferromagnetic and antiferromagnetic Fe/Cr superlattices. The exchange-spring system is a bilayer structure made of hard Sm-Co and soft Fe ferromagnetic layers. The magnetic properties were investigated using the magneto-optic Kerr-effect during repeated reversal of the soft layer magnetization by field cycling up to 10⁷ times. The experimentally observed decay behaviors are discussed in terms of microstructure and spin configuration of the pinning layers.
