Abstract

The exquisite sensitivity of magnetic resonance force microscopy (MRFM) was exploited and demonstrated a detection sensitivity equivalent to two spins in a 0.1 Hz measurement bandwidth. This represents nearly 2 orders of magnitude improvement over previous MRFM results. As such, the technique was applied to spin ensembles consisting of fewer than 10² electron spins and study statistical polarizations of order 10 spins.
