The results of a study of the magnetically ordered phase of a CuCrO2 single crystal by the NMR method on 53Cr nuclei in the absence of an external magnetic field are presented for the first time. The 53Cr NMR spectrum is observed in the frequency range vres = (61 - 66) MHz, and its shape depends on the delay between pulses tdel in the pulse sequence τπ / 2 – tdel – τπ – tdel – echo. Spin-spin and spin-lattice relaxation times were measured, components of the electric field gradient, hyperfine fields, and magnetic moment on chromium atoms were estimated.
