Reduction of Magnetic Noise in Magnetic Resonance Force Microscopy
arXiv:cond-mat/0309158 · doi:10.1103/PhysRevB.69.212408
Abstract
We study the opportunity to reduce a magnetic noise produced by a uniform cantilever with a ferromagnetic particle in magnetic resonance force microscopy (MRFM) applications. We demonstrate theoretically a significant reduction of magnetic noise and the corresponding increase of the MRFM relaxation time using a nonuniform cantilever.
