Nuclear magnetic resonance force microscopy (NMRFM) is a technique that combines aspects of scanning probe microscopy (SPM) and nuclear magnetic resonance (NMR) to obtain 3 dimensional nanoscale spatial resolution and perform spectroscopy. We describe the components of a helium-3 NM-RFM probe and studies of ammonium sulfate ((NH4)2SO4) and magnesium dibordie (MgB2). For our room temperature (NH4)2SO 4 studies we were able to perform a 1-D scan and perform nutation and spin echo experiments. In our 77 K MgB2 we demonstrate a 1-D scan of a 30 mum powder sample. In addition, we describe magnetic measurements of the possible dilute semiconductors MnxSc 1-xN and Fe0:1Sc 0:9N. |
