零场和纵场介子自旋弛豫(ZF-AND)测量结果表明，在常压下零场下的磁相变温度为2.85K。在2.3K的常压下，观察到0.5kbar以上的自旋自发进动，表明存在长程相干序。在常压下，测量证实了静态内磁场的存在，但在0.29K以下没有观察到转动信号。这些结果表明Iimamura[Phys.Rev.B74,064423(2006年)]是从短程有序到长程相干有序的连续变化。
Zero- and longitudinal-field muon spin relaxation (ZF- and) measurements were carried out in pressures up to 2 kbar in impurity-dopedof which the magnetic phase-transition temperature under ambient pressure in zero field is 2.85 K. The spontaneous muon spin precession, which indicates the existence of a long-range coherent order, is observed above 0.5 kbar at 2.3 K. In ambient pressure, the existence of the static internal magnetic field is confirmed bymeasurements, however, no rotational signal is observed down to 0.29 K. These results indicate that the crossover reported by IImamura [Phys. Rev. B 74, 064423 (2006)] is the continuous change from a short-range order to a long-range coherent order.
