Autor: M.V. Chaparala, J.P. Ulmet, S. Askenazy, A. Narjis, R. Richter, Michael J. Naughton
Publikováno v: Physica B: Condensed Matter. :125-128
The technique of cantilever magnetometry has been extended to pulsed magnetic fields. Using micromachined single-crystal silicon cantilevers and capacitance detection, a utilizable sensitivity of ∼10 −12 Am 2 in fields up to 36 T has been achieve
