    Abstract

    We report a cantilever resonance frequency shift due to the magnetic resonance force gradient in magnetic resonance force microscopy. Our experimental results obtained for a phantom sample of diphenylpicrylhydrazil (DPPH) at T = 14K can be quantitatively understood with the magnetic force gradient containing the first derivative of spin magnetization. This substantial contribution should be explicitly treated when calculating an equipment function and estimating the number of spins through the deconvolution process for image restoration.
