Spin transfer magnetization switching magnetic element formed of ferrimagnetic rare earth transition metal (RE-TM) alloy

摘要

A magnetic tunnel junction (MTJ) is a free layer formed from a ferrimagnetic RE-TM alloy having a net moment occupied by the sublattice moment of the rare earth (RE) composition of the rare earth transition metal (RE-TM) alloy. Including. MTJ is a pinned layer formed from a RE-TM alloy having a net moment occupied by the sublattice moment of the rare earth (RE) composition of the rare earth transition metal (RE-TM) alloy, the pinned layer being free And further comprising one or more amorphous thin insertion layers such that the net magnetic moment of the layer and pinned layer is low or near zero.
