Abstract:
1. A magnetic device, comprising: a substrate, comprising: a bottom electrode; a registration layer configured to store data; and a barrier layer disposed on the registration layer; a sensing block which is patterned to be distributed on the barrier layer of the substrate; and a repair layer disposed conformal to the substrate and the sensing block; wherein the barrier layer of the substrate is configured to have a tunneling effect when a bias voltage exists between the sensing block and the registration layer, and the oxygen concentration in the barrier layer is lowered after coming in contact with the repair layer, wherein the repair layer comprises metal oxide, wherein the sensing block comprises a first ferromagnetic layer made with IMA (In-plane Magnetic Anisotropy) on to the barrier layer, a non-magnetic layer disposed on the first ferromagnetic layer, a second ferromagnetic layer made with IMA on the non-magnetic layer, and an anti-ferromagnetic layer made with IMA on the second ferromagnetic layer.
