Hall resistivities ρ H, the magnetizations M and the magnetoresistances Δρ have been measured as functions of the applied magnetic field H in the wide temperature range for ferromagnetic systems of CuCr 2S 4, Cu 0.5Zn 0.5Cr 2Se 4 and Cr 3Te 4, which are considered to have non-trivial spin structures below the temperature T m. For CuCr 2S 4 and Cr 3Te 4, the Hall resistivities have been found to deviate from the ordinary expression ρ H = R 0H + 4πR sM 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 has also been observed for all the systems. These behaviors are discussed in relation to their possibly non-trivial magnetic structures.
