説明
Hall resistivities ρH, 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 CuCr2S4, Cu0.5Zn0.5Cr2Se4 and Cr3Te4, which are considered to have non-trivial spin structures below the temperature Tm. For CuCr2S4 and Cr3Te4, the Hall resistivities have been found to deviate from the ordinary expression ρH=R0H+4π RsM below Tm, where R0 and Rs are the ordinary and anomalous Hall coefficients, respectively. The sign change of Rs with T has also been observed for all the systems. These behaviors are discussed in relation to their possibly non-trivial magnetic structures.
