  Co3Sn2S2, a quasi-two-dimensional system with kagome lattice, has been found
as a magnetic Weyl semimetal recently. In this work, the anisotropies of
magnetization and transport properties of Co3Sn2S2 were investigated. The high
field measurements reveal a giant magnetocrystalline anisotropy with an
out-of-plane saturation field of 0.9 kOe and an in-plane saturation field of
230 kOe at 2 K, showing a magnetocrystalline anisotropy coefficient Ku up to
8.3 * 10^5 J m-3, which indicates that it is extremely difficult to align the
small moment of 0.29 {\mu}B/Co on the kagome lattice from c axis to ab plane.
The out-of-plane angular dependences of Hall conductivity further reveal strong
anisotropies in Berry curvature and ferromagnetism, and the vector directions
of both are always parallel with each other. For in-plane situation, the
longitudinal and transverse measurements for both I parallel a and I
perpendicular a cases show that the transport on the kagome lattice is
isotropic. These results provide essential understanding on the magnetization
and transport behaviors for the magnetic Weyl semimetal Co3Sn2S2.
