- 論文の詳細を見る
Recent experimental studies on NaTi0. and Limit, suggest that they mightbe rare compounds of 20 triangular lattice antiferromagnet with .5:: 1 /2,the formerbeing Heisenberg-like and the latter being Ising-like. We have studied ESR from1.5 K to 300 K. In NaTi0. a broad F,SR signal was observed at 300 K. A sharpESR signal grows below x 250 K and continues to increase the intensity toward0 K. In Limit., we found clear dip in resonance width at 210 K correspondingto the para- to ferrimagnet-like transition but no change in resonance field onpassing through it. Contrary to this, a remarkable divergence of the width wasfound at - 19 K and a shift of resonance field starts below it, though no magneticorder has been detected by ncutron scattering. Possible origin of these phenomenais discussed.
