为了研究等边三角形自旋管反铁磁体CsCrF_4中三个不等价的~（19）F位的超精细耦合，我们测量了20 K以上顺磁态~（19）F-NMR Knight位移随温度的变化。三个F位的超精细耦合常数分别为−0.170、0.280和−0.045 T/μB，与1.65 K时的光谱一致，表明体系可能处于有序态.
In order to investigate the hyperfine coupling of three inequivalent19F sites in the equilateral triangular spin-tube antiferromagnet CsCrF4, we have measured the temperature dependence of19F-NMR Knight shift in the paramagnetic state above 20K. The hyperfine coupling constants for three F-sites were determined to be−0.170, 0.280 and−0.045 T/μB, and were found to be consistent with the observed spectra at 1.65K, where the system is possibly in the ordered state.
