Magnetic order in the structurally disordered helicoidal magnet Cr1/3NbS2: NMR at 53Cr nuclei
Abstract
The Cr1/3NbS2 magnet is studied by nuclear magnetic resonance (NMR) at 53Cr nuclei in a zero applied magnetic field. The following two frequency ranges are distinguished in the 53Cr NMR spectrum at T = 4.2 K: ν 1 = 64-68 MHz and ν 2 = 49-51 MHz. They can be related to two valence states of chromium ions, namely, Cr4+ and Cr3+. 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.
