Magnetic resonance in an ensemble of laser-cooled trapped Rb atoms is excited using a micro cantilever with a magnetic tip. The cantilever is mounted on a multi-layer atom chip designed to capture, cool, and magnetically transport cold atoms. The coupling is observed by measuring the loss from a magnetic trap as the oscillating cantilever induces Zeeman state transitions in the atoms. Interfacing cold atoms with mechanical devices could enable probing and manipulating atomic spins with nanometer spatial resolution and single-spin sensitivity, leading to new capabilities in quantum computation, quantum simulation, or precision sensing.
