Claim 19:
20. A heat-assisted magnetic recording head comprising:
a first feature comprising a first primary metal,
a second feature comprising:
an oxide region; and
a mixed metal oxide adhesion layer, and

a bilayer adhesion structure comprising:
the mixed metal oxide adhesion layer of the second feature; and
a metal adhesion layer comprising a second primary metal that is different than the first primary metal,

wherein the first feature, the metal adhesion layer, the mixed metal oxide adhesion layer, and the oxide region are provided in a layered configuration along a layering axis,
wherein a first surface of the mixed metal oxide adhesion layer is adhered to a surface of the oxide region,
wherein a first surface of the metal adhesion layer is adhered to a second surface of the mixed metal oxide adhesion layer,
wherein a surface of the first feature is adhered to a second surface of the metal adhesion layer,
wherein the second surface of the mixed metal oxide adhesion layer comprises an element, and
wherein the oxide region comprises an oxide of the element.
