Crystals listed in the JCPDS card in BaO‐B2O3‐Al2O3 and BaO‐B2O3‐Ga2O3 systems were synthesized by means of a solid‐state reaction method and a liquid‐state reaction method. Synthesized crystals were characterized from a viewpoint of Second Harmonic Generation (SHG) and crystal growth possibility. Ba5Al4B12O29 and Ba5Ga4B12O29 are promising new candidate crystals from the viewpoint of SHG activity and congruent melting behavior. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) 相似文献

Positive muon spin relaxation measurements were performed on a spin-1/2 system BaVS3, which shows a metal-insulator transition at TMI= 70 K. We found a marked muon-spin depolarization below TX= 30 K without appreciable critical divergence. The possibility of muonium formation in the insulating state rather than electron
spin freezing is discussed taking into account the quenching of V spins evidenced by 51V NMR and NQR measurements.

This article reports the accumulation effect of the 3He originating from tritium β decay; 3He created in solid remains in it, while one in liquid diffuses and goes out to the vapor gas. We observed this effect through
the neutron detection from muon catalyzed fusion phenomenon (μCF), and gave it qualitative understanding, by which the muon
transfer rate from (dμ) and (tμ) to helium was derived.
