Magnetic devices with magnetic and getter regions and methods of formation

A magnetic device, comprising:

• a magnetic tunnel junction sub-structure comprising:
• a free region exhibiting a switchable magnetic orientation;
• and
• a fixed region exhibiting a fixed magnetic orientation;
• an oxide region adjacent the free region;
• and
• a getter region in physical contact with the oxide region and comprising:
• an oxygen-getter species bonded to oxygen diffused from the oxide region;
• and
• at least one other getter species bonded to a species diffused from the free region.

A method of forming a magnetic device, the method comprising:

• forming a precursor structure on a substrate, comprising:
• forming a precursor getter material over the substrate, the precursor getter material comprising a first getter species and a second getter species;
• forming a precursor oxide material over the precursor getter material;
• forming a precursor magnetic material over the precursor oxide material;
• and
• forming another oxide material over the precursor magnetic material;
• annealing at least a portion of the precursor structure to diffuse a species from the precursor oxide material to bond with the first getter species and to diffuse a species from the precursor magnetic material to bond with the second getter species;
• and
• patterning the precursor structure to form at least one structure of the magnetic device, the at least one structure comprising a magnetic region formed from the precursor magnetic material and exhibiting a switchable magnetic orientation.
