Cosmological observations imply the existence of dark matter, which cannot be one of the Standard Model particles. High energy physics models, such as the Peccei-Quinn symmetry and grand unified theories, incorporate light pseudoscalar bosons (axion-like particles, ALPs), which are potential dark matter candidates. Using solid state nuclear magnetic resonance, the second generation of CASPEr-electric probes ALP dark matter with mass near 10 neV. Experimental sensitivity was calibrated with small-tip angle pulses. The theoretical basis and experimental setup of this and the following CASPEr-e generation will be provided in this talk.
