22 Mar 2017 | | Abstract: | We have fabricated ferrite cantilevers in which their vibrational properties
can be controlled by external magnetic fields. Submicron-scale cantilever
structures were made from Y3Fe5O12 (YIG) films by physical etching combined
with use of a focused ion beam milling technique. We found that the cantilevers
exhibit two resonance modes which correspond to horizontal and vertical
vibrations. Under external magnetic fields, the resonance frequency of the
horizontal mode increases, while that of the vertical mode decreases,
quantitatively consistent with our numerical simulation for magnetic forces.
The changes in resonance frequencies with magnetic fields reach a few percent,
showing that efficient magnetic control of resonance frequencies was achieved. | | Source: | arXiv, 1703.7533 | | Services: | Forum | Review | PDF | Favorites | |
