Magnetic device having a magnetic material in a contact structure coupled to a magnetic element and method of manufacture thereof

摘要

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.

1. A magnetic device, comprising:
a magnetic multilayer structure having one or more free layers and one or more reference layers, said one or more free layers and said one or more reference layers each having a magnetization direction that is substantially perpendicular to its plane; a contact structure electrically coupled to the magnetic multilayer structure, the contact structure having a magnetic material therein configured to exert a magnetic field on the one or more free layers of the magnetic multilayer structure, said magnetic material having a substantially perpendicular magnetic anisotropy (PMA).
