摘要：

Hall resistivities rho (H), the magnetizations M and the, magnetoresistances Deltap have been measured as functions of the applied magnetic field H in the wide temperature range for ferromagnetic Systems Of CuCr2S4, Cu0.5Zn0.5Cr2Se4 and Cr3Te4, which are considered to have non-trivial spin structures below the temperature T-m. For CuCr2S4 and Cr3Te4, the Hall resistivities have been found to deviate from the ordinary expression rho (H) = R0H + 4 piR(s)M below T-m where R-0 and R-s are the ordinary and anomalous Hall coefficients, respectively. The sign change of R-s with T-m has also been observed for all the systems. These behaviors are discussed in relation to their possibly nontrivial magnetic structures.
