摘要:
Magnetic random access memory (MRAM) devices and techniques for use thereof are provided. In one aspect, a magnetic memory cell is provided. The magnetic memory cell comprises at least one fixed magnetic layer; at least one first free magnetic layer separated from the fixed magnetic layer by at least one barrier layer; at least one second free magnetic layer separated from the first free magnetic layer by at least one spacer layer; and at least one capping layer over a side of the second free magnetic layer opposite the spacer layer. One or more of the first free magnetic layer and the second free magnetic layer comprise at least one rare earth element, such that the at least one rare earth element makes up between about one percent and about 10 percent of one or more of the first free magnetic layer and the second free magnetic layer.
