A microscopic garnet crystal was the key to unlocking the torque-mixing magnetic resonance spectroscopy technique. A focused gallium ion beam sculpted the single-crystal, one micrometer diameter yttrium iron garnet disk from within a much larger starting piece of the magnetic gemstone. The image is an angled-perspective scanning electron micrograph, showing the microdisk before it was placed on the nanomechanical sensor with which precise mechanical torque signatures of magnetic resonance were observed.
