Formatted abstract
A cavity optomechanical magnetometer is demonstrated. The magnetic-field-induced expansion of a magnetostrictive material is resonantly transduced onto the physical structure of a highly compliant optical microresonator and read out optically with ultrahigh sensitivity. A peak magnetic field sensitivity of 400nTHz -1 /2 is achieved, with theoretical modeling predicting the possibility of sensitivities below 1pTHz -1 /2. This chip-based magnetometer combines high sensitivity and large dynamic range with small size and room temperature operation
