A magnetic tunnel junction having a compensation element is disclosed. The magnetic tunnel junction includes a synthetic antiferromagnetic reference element, and a synthetic antiferromagnetic compensation element having an opposite magnetization moment to a magnetization moment of the synthetic antiferromagnetic reference element. A free magnetic layer is between the synthetic antiferromagnetic reference element and the synthetic antiferromagnetic compensation element, and an electrically insulating and non-magnetic tunneling barrier layer separates the free magnetic layer from the synthetic antiferromagnetic reference element. The free magnetic layer includes Co100-X-YFeXBY wherein X is a value being greater than 30 and Y is a value being greater than 15.
