Description
Magnetic resonance is a versatile tool for searching for axion-like dark matter. CASPEr is one example of this approach. I will focus on the quantum limits on the sensitivity of magnetic-resonance-based searches, emphasizing the importance of evading back action on the spin ensemble from the sensor used to detect its dynamics [1]. I will also discuss schemes that have potential for achieving sensitivity beyond the spin projection noise limit, and their experimental feasibility.
