Abstract
A magnetic device has a contact structure including a magnetic material therein. The contact structure is magnetostatically and/or electrically coupled to a magnetic element such as one having a magnetic tunneling junction (MTJ) multilayer structure. The magnetic material included in the contact structure is configured to compensate for an offset field acting on the free layer of the magnetic element by reference layers of the magnetic element.
