Contribution
It introduces a novel approach of employing a nonuniform cantilever to lower magnetic noise in MRFM, which was not previously explored.
Findings
Significant reduction of magnetic noise theoretically demonstrated.
Increase in MRFM relaxation time predicted.
Potential for improved measurement sensitivity in MRFM applications.
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.
