  The magnetization process of single crystals of the metallic kagom\'e
ferromagnet Co3Sn2S2 was carefully measured via magnetization and AC
susceptibility. Field-dependent anomalous transitions in the magnetization
indicate a low-field unconventionally ordered phase stabilized just below TC.
The magnetic phase diagrams in applied fields along different crystallographic
directions were determined. The magnetic relaxation process studied in
frequencies covering five orders of magnitude from 0.01 to 1000 Hz indicates
characteristic relaxation times of several seconds at the boarders of the
anomalous phase. Our results arise a lot of questions about the nature of
Co3Sn2S2 magnetic states.
