Abstract Pulsed and continuous wave NMRON, and NMR thermally detected by Nuclear Orientation have been used to investigate the magnetic properties of the quasi-2-dimensional ferromagnet 54Mn-Mn(COOCH3)·4H2O. The NMR frequencies of both the 54Mn spins and the abundant 55Mn spins have been determined for the two crystalline lattice sites Mn1 and Mn2. The line widths of the 54Mn resonances are homogeneously broadened to about 300 kHz, and the 55Mn resonances are significantly pulled down in frequency. The spin-lattice relaxation times in low applied magnetic fields are short with T1 for the Mn2 site being much less than the value for the Mn1 site. Level crossing is observed between the Mn1 and Mn2 resonances in an applied field of 2.6 T.
