The magnetic structure of the Fe2P-type R6CoTe2 phases (R = Gd-Er, space group P (6) over bar 2m) has been investigated through magnetization measurement and neutron powder diffraction All phases demonstrate high-temperature ferromagnetic and low-temperature transitions T-C = 220 K and T-CN = 180 K for Gd6CoTe2, T-C = 174 K and T-CN = 52 K for Tb6CoTe2, T-C = 125 K and T-CN = 26 K for Dy6CoTe2, T-CN = 60 K and T-N = 22 K for Ho6CoTe2 and T-CN similar to 30 K and T-N similar to 14 K for Er6CoTe2
