Query: Spin Microscope Based on Optically Detected Magnetic Resonance   We propose a scanning magnetic microscope which has a photoluminescence
nanoprobe implanted in the tip of an AFM or STM, or NSOM, and exhibits
optically detected magnetic resonance (ODMR). The proposed spin microscope has
nanoscale lateral resolution and the single spin sensitivity for AFM and STM.
