We study properties of UNI,tB using the Heisenberg model. Considering the spin operators asclassical vectors, we show that the classical grotund state of this model is the vortexlike U spinarrangeunent in the basal plain. By means of' the spin-wave n?ethod we calculate the tenaperaturedependence of the specific heat at low temperatures, and estinxate the coupling constants. Fromthe obtained coupling constants we get the transition temperattrre Ty : 8.7 K.
