Magnetoelectric device, method for forming a magnetoelectric device, and writing method for a magnetoelectric device
First Claim
1. A magnetoelectric device comprising:
- a reference magnetic layer structure having a fixed magnetization orientation; and
a synthetic antiferromagnetic layer structure comprising a free magnetic layer structure and a coupling magnetic layer structure antiferromagnetically coupled to each other, each of the free magnetic layer structure and the coupling magnetic layer structure having a magnetization orientation that is variable; and
an insulating layer arranged in between the free magnetic layer structure and the reference magnetic layer structure;
wherein the insulating layer is configured to prevent the free magnetic layer structure being subjected to spin-transfer torque effect; and
wherein the reference magnetic layer structure and the synthetic antiferromagnetic layer structure are arranged one over the other.
