| Popis: | The muon spin relaxation (μSR), which uses spin-polarized muons to probe tiny local field in matters, is a useful tool for studying spin-related phenomena in magnets, superconductors and semiconductors, etc. Here we report a first successful application to ferroelectrics. We utilized μSR to detect a ferroelectric transition in a newly-identified ferroelectric material Co2(OD)3Cl. The deuteriums in Co2(OD)3Cl were found to be rapidly fluctuating in the paraelectric phase at high temperatures, then they drastically slowed down toward the ferroelectric transition at = 229 K, and eventually became quasi-static at around 160 K. Our study reveals that Co2(OD)3Cl is a deuterium-order ferroelectric material, and detailed analysis suggests that it can be viewed as new type of multiferroic material. The present study demonstrates that the conventional μSR can be an effective and powerful tool for ferroelectrics study. |
