Abstract

An apparatus for scanning over a surface of an arbitrarily sized sample in magnetic resonance force microscopy comprising a cantilever for holding a magnetic particle at the cantilever tip, an RF antenna, positioned around the cantilever, for emitting an RF magnetic field across a portion of the sample causing spin of particles in the sample to reverse attracting and opposing the magnetic particle at the cantilever tip, an optical fiber, positioned close to the cantilever tip, for measuring displacements of the cantilever tip where the RF antenna, cantilever, magnetic particle and optical fiber are in fixed positions relative to each other and the sample is positionable according to a sample stage.
