摘要：

Magnetic transitions and magnetotransport properties of polycrystalline Er1-xGdxMn6Ge6(x=0.2-0.9) compounds were studied.The magnetic and resistivity properties were analyzed in an applied magnetic field up to 5 T.It is found that Er1-xGdxMn6Ge6(x=0.2-0.9) compounds displays a transition from the antiferromagnetic state to the ferrimagnetic state for increasing Gd content.The Er1-xGdx Mn6Ge6 with x=0.2 and 0.5 compounds order antiferromagnetically at 430 and 432 K,respectively.The Er1-x GdxMn6Ge6 with x=0.8 and 0.9 compounds order ferrimagnetically at 462 and 471 K,respectively.The Er1-xGdxMn6Ge6 compounds undergo the second transitions below 71 K.The magnetoresistance curves of the Er0.1Gd0.9Mn6Ge6 compound in a field of 5 T are presented and the magnetoresistance effects are related to the metamagnetic transitions.
