"F NMR in a two dimensional Heisenberg ferromagnet K.CuF. has beenstudied down to 30 mK at zero or small external fields. Below 1 K the NMRsignals show anomalous behavior, which can be explained satisfactorily, bysolving the coupled equations of motion for four "F nuclear spins and an elec-tron spin, whose ferromagnetic resonance frequency is nearly equal to zero.Furthermore, below 90 mK, a new strong spin echo signal appeared at 54.5 MHzunder a slightly different excitation condition. The origin and nature of this.J .new s?gnal IS dufficult to understand at present.
