The temperature dependence of the easy axis magnetization in the ferromagneticphase of MnP is measured to an accuracy of A M/ M< f5 x 10 ' over a rangefrom 4.2 K to 280 K. Instead of the usual T"' law, 7'ln T dependence holds upto about T./2. The following spin wave dispersion is expected to exsist at 0 K ;along the a axis it is nearly constant up to q.= Q and increases very rapidly beyondQ, where Q is the screw propagation vector, while for perpendicular to the a axisit is quadratic in q.. At a finite temperature, the calculated two-magnon renor-malization causes increase of the magnon energy near q.xQ which induces ananomalous suppression for decrease of magnetization in MnP. The ferro-screwphase transition seems also to be due to this effect.
