| 研究実績の概要 |
In this year we have performed Transverse-field muSR experiment on k-HgBr for the first time (in the perpendicular mode) obtaining in-plane penetration depth order parameter. The additional measurement is necessary to improve signal-noise ratio. We got our following muSR proposal approved and plan to add the sample mass.
In the k-HgCl Zero-field muSR measurement also has been done in k-HgCl down to 25 miliK for the first time. There is no obvious signature of long-range ordered.
Furthermore, we have developed a technique to measure dc-susceptibility for this series samples (plate-like shape crystal) to get a precise temperature dependence of susceptibility. We aim to report the plot of muon Knight shift vs susceptibility, comparing between those in k-HgBr and k-HgCl.

2: おおむね順調に進展している
理由
The penetration depth measurement needs to be improved to get solid and complete data set, although we earned the high-priority muSR beamtime at TRIUMF Canada from the proposal submission in January 2023.

| 今後の研究の推進方策 |
2023: We will perform Transverse-field muSR at TRIUMF in k-HgBr. The measurement at ISIS and JPARC is slightly shifted to 2024.
2024: Writing up main papers and execute a continuation.
