Devices, systems and methods including magnetic structures and micromechanical structure

A magnetic device comprising:

• a cap on a substrate;
• a micromechanical structure between the substrate and the cap, the micromechanical structure comprising a patterned layer of magnetic material and a rotatable platform, wherein the micromechanical structure is part of a micromechanical scanner, and wherein the rotatable platform comprises a reflective layer on an opposite side of the rotatable platform from the patterned layer of magnetic material;
• and
• a magnetic structure on the cap, wherein the magnetic structure is configured to interact magnetically with an environment of the magnetic device, and wherein the magnetic structure and the patterned layer of magnetic material are configured to interact magnetically.

A magnetic device comprising:

• a cap on a substrate;
• a micromechanical structure between the substrate and the cap, the micromechanical structure comprising a patterned layer of magnetic material;
• and
• means for magnetically interacting with the patterned layer of magnetic material and an environment of the magnetic device so as to modify a magnetic stimulus that is external to the magnetic device, wherein the micromechanical structure is configured to respond to the modified magnetic stimulus, and wherein the means for magnetically interacting are on the cap and comprise patterned magnetic material.
