title = "Phase-locked cantilever magnetometry",
abstract = "We describe a feedback-based dynamic cantilever magnetometry technique capable of achieving thermal limited magnetic moment sensitivity with low applied fields. Using this technique, we have observed periodic entry of vortices into mesoscopic Sr2 RuO4 rings. The quantized jump in the magnetic moment of the particle produced by individual vortices was measured with a resolution of 7× 10-16 emu with an applied field of 1 Oe.",
