The Cr{sub 1/3}NbS{sub 2} magnet is studied by nuclear magnetic resonance (NMR) at {sup 53}Cr nuclei in a zero applied magnetic field. The following two frequency ranges are distinguished in the {sup 53}Cr NMR spectrum at T = 4.2 K: ν{sub 1} = 64–68 MHz and ν{sub 2} = 49–51 MHz. They can be related to two valence states of chromium ions, namely, Cr{sup 4+} and Cr{sup 3+}. The components of the electric field gradient, the hyperfine fields, and the magnetic moment at chromium atoms are determined. The NMR data demonstrate that the magnetic moments of chromium lie in plane ab and form a magnetic structure consisting of regions with a helicoidal magnetic order and regions where this order is broken.
