Phys. Rev. Lett. 94, 207601 (2005) [4 pages]Microscale Localized Spectroscopy with a Magnetic Resonance Force MicroscopeReceived 28 January 2005; published 26 May 2005 Magnetic resonance force microscopy is combined with spin-echo spectroscopy to obtain spatially and spectrally resolved NMR signals of micrometer-scale objects. The experimental spatial resolution for the demonstration experiment on a sample consisting of Ba(ClO3)2·H2O and (NH4)2SO4 single crystals is 3.4 μm. The spectral resolution of 3.4 kHz is sample limited. Improvements in resolution and extensions of the method to more than one spatial dimension and to multidimensional spectroscopy are possible. © 2005 The American Physical Society URL:
