ABSTRACT
Trilayers consisting of ferromagnetic rare earth and transition metals show an antiparallel exchange coupling of the individual layers. Thus, they can be exploited as hardmagnetic electrodes in spin valve stacks and magnetic tunnel junctions for sensors or memories. Magnetic tunnel junctions consisting of IrMn exchange-biased NiFe/Gd/NiFe trilayers show a compensation of the total magnetic moment at an appropriate choice of the individual layer thicknesses and temperature. This stack setup allows a sixfold enhancement of the exchange-bias field and a strong reduction of the Néel and edge stray field coupling in patterned elements. Therefore, such trilayers are proposed as an alternative for artificial ferrimagnets in the relevant devices. © 2003 American Institute of Physics.
