Precise measurements of the temperature dependence of the electrical resistivity and thermo-power were performed for a series of samples of the system Ni1-xZnxFe2O4 (x = 0.2, 0.4 and 0.6). Observed changes around the Curie temperature confirm previously reported data for Cu-Cd ferrite and were explained as being due to the fairly strong B-B exchange interaction in these ferrites
