A method for forming a modified resonator is provided. In one aspect, the method includes obtaining a resonator on top of a substrate, thereby forming an interface area between a bottom surface of the resonator and a top surface of the substrate. The resonator can include niobium or tantalum. The method also includes contacting the resonator and the substrate with a liquid acidic etching solution selected so as to have a higher etch rate towards the substrate than towards the resonator and a nonzero etch rate towards the resonator.

Resonators

In one aspect, the disclosed technology relates to a magnetic device, which may be a magnetic memory and/or logic device. The magnetic device can comprise a seed layer; a first free magnetic layer provided on the seed layer; an interlayer provided on the first free magnetic layer; a second free magnetic layer provided on the interlayer; a tunnel barrier provided on the second free magnetic layer; and a fixed magnetic layer. The first free magnetic layer and the second free magnetic layer can be ferromagnetically coupled across the interlayer through exchange interaction.
