摘要
The magnetic properties of an intermetallic compound ErTi2Ga4 with the tetragonal (I4/mmm) structure was investigated. The magnetic measurements on the poly- and single crystalline specimens have shown that the compound is a ferromagnet with T-c of 10 X and the ordered magnetic moment (mu = 9 mu (B)/f.u.) parallel to the a-axis. It was found also that the magnetic isotherms of polycrystalline ErTi2Ga4 do not obey the Arrot's relationship (linearity between M-2 and H/M), which suggests that the coupling of the moment fluctuation is quite weak in this system.
