The antiferromagnetic resonance in thin single-crystal plates of MnCO<sub>3</sub> was studied at omega <sub>p</sub>/2 pi =9.3 GHz and T=4.2-10 K for large values of the angle theta between the static magnetic field H and the basal plane of the crystals. A set of quasi-equidistant absorption lines was observed for a wide range of magnetic fields H, which can be attributed to the size effect: the resonances of plane spin-waves with different wavevector values, mod k mod approximately=10<sup>5</sup> cm<sup>-1</sup>, standing perpendicularly to the crystal plate. The relaxation of the spin-waves was evaluated from the width of individual resonance lines, and found to amount to Delta omega <sub>k</sub>/2 pi approximately=0.03 MHz at T=4.2 K. |
