CuO$$_{2}$$リボン鎖系Cs$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$は、同様の構造を持つRb$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$とは異なる磁気的基底状態をとる。そこで本報では、比熱測定によって、新たにCs$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$の磁気相図を作成した。その結果、ゼロ磁場中ではT$$_{N}$$=1.85Kで反強磁性体の磁気転移を示すことが分かった。さらに中性子散乱実験によってCs$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$の磁気構造と結晶構造を決定し、Rb$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$との違いを議論する。

Magnetic phase diagram was investigated by the specific heat measurement and magnetic structure has been studied by using neutron diffraction for Cs$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$ with CuO$$_{2}$$ ribbon chains. We found that this material showed antiferromagnetic transition at T$$_{N}$$ = 1.85 K under 0 magnetic field. The difference in magnetic and crystal structure between Cs$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$ and Rb$$_{2}$$Cu$$_{2}$$Mo$$_{3}$$O$$_{12}$$ are discussed.
