| Abstract: | The low temperature structural phase transition occuring in EuMo6S8 was also detected, by specific heat measurements, in bulk samples of M Mo6S8 with M=Ba, Sr and Ca. Sintered material of EuMo6S8 equally transforms, but in a broad temperature interval. The triclinically distorted phases are characterized by a very low electronic densities of states. |
