Magnetic element having low saturation magnetization

A device comprising:

• one or more magnetic memory cells, each one of the magnetic memory cells including:
• a magnetic element including:
• a first fixed layer having a fixed layer magnetization;
• a first spacer layer that is nonmagnetic;
• and
• a first free layer having a free layer magnetization that is changeable due to spin transfer when a write current above a threshold is passed through the first free layer;
• the first spacer layer residing between the first fixed layer and the first free layer,
• the first free layer including at least one ferromagnetic material and at least one nonmagnetic material, wherein the at least one nonmagnetic material is selected from a group consisting of W, Ti, V, and Hf to lower the threshold of the write current for the first free layer including the at least one nonmagnetic material compared to the first free layer not including the at least one nonmagnetic material;
• and
• a circuit comprising at least an isolation transistor electrically connected to the magnetic element to control the write current through the magnetic element.
