Abstract:
In one aspect, the disclosed technology relates to a magnetic device, which may be a magnetic memory and/or logic device. The magnetic device can comprise a seed layer; a first free magnetic layer provided on the seed layer; an interlayer provided on the first free magnetic layer; a second free magnetic layer provided on the interlayer; a tunnel barrier provided on the second free magnetic layer; and a fixed magnetic layer. The first free magnetic layer and the second free magnetic layer can be ferromagnetically coupled across the interlayer through exchange interaction.
