Abstract:	We report the results of an experimental search for ultralight axion-like dark matter in the mass range 162 neV to 166 neV. The detection scheme of our Cosmic Axion Spin Precession Experiment (CASPEr) is based on a precision measurement of $^{207}$Pb solid-state nuclear magnetic resonance in a polarized ferroelectric crystal. Axion-like dark matter can exert an oscillating torque on $^{207}$Pb nuclear spins via the electric-dipole moment coupling $g_d$, or via the gradient coupling $g_{ ext{aNN}}$. We calibrated the detector and characterized the excitation spectrum and relaxation parameters of the nuclear spin ensemble with pulsed magnetic resonance measurements in a 4.4~T magnetic field. We swept the magnetic field near this value and searched for axion-like dark matter with Compton frequency within a 1~MHz band centered at 39.65~MHz. Our measurements place the upper bounds ${\|g_d\|<7.0 imes10^{-4}, ext{GeV}^{-2}}$ and ${\|g_{ ext{aNN}}\|<2.1 imes10^{-1}, ext{GeV}^{-1}}$ (95\% confidence level) in this frequency range. The constraint on $g_d$ corresponds to an upper bound of ${7.6 imes 10^{-22}, ext{e}cdot ext{cm}}$ on the amplitude of oscillations of the neutron electric dipole moment, and ${3.2 imes 10^{-6}}$ on the amplitude of oscillations of CP-violating $ heta$ parameter of quantum chromodynamics. Our results demonstrate the feasibility of using solid-state nuclear magnetic resonance to search for axion-like dark matter in the nano-electronvolt mass range.
