Abstract

We have studied the room temperature nuclear magnetic relaxation in anisotropic antiferromagnet using a wide range of NMR (nuclear magnetic resonance) field. Being a system of dense paramagnetic ions at room temperature, shows some features that can be expected from dilute paramagnetic systems, as well as some results that drastically deviate from the dilute paramagnetic approximations. Besides, nuclei exhibit an anomalous deviation in the spin-lattice relaxation time () around the field of 0.7 T.
