The measurements at room temperature showed the minimum of Iinewidthsat a "magic angle" #=55' and the change of line shapes with decreasing Mmcontent, where 0 is the angle between an external magnetic field and the c axis ofthe crystal. These facts were explained by the donninancy of @=0 mode in the dipo-tar interaction and the change of spin correlations from two- to one-dimensionalcharacter.In the samples of concentration c>c, where c, is a pefcolation concentration,the minimum of the linewidths at the magic angle disappeared in low temperaturesand the resonances disappeared at N<Set temperature. In the samples of c<c,the minimum at the magic angle did not disappeared and the resonances wereobserved inspite of sharp broadening at the lowest temperature that could bereached.
