摘要：

Investigations in the (Mg,Ca)-Mn-Sn system lead us to obtain new HfFe6Ge6-type Mg1-xCaxMn6Sn6 compounds (0 less than or equal to x less than or equal to 0.7). They order ferromagnetically between 290 K for x=0.0 to 253 K for x=0.6. The maximum magnetization value at 4.2 K ranges between 11.3 and 12.6 mu(B) mol(-1). The changes of magnetic properties between ferromagnetic alkaline earth compounds and antiferromagnetic rare earth compounds are discussed. (C) 1998 Elsevier Science S.A.
