X-ray diffraction studies carried out on a Ho{sub 0.85}Tb{sub 0.15}Fe{sub 2{minus}{ital x}}Co{sub {ital x}} ({ital x}=0--2.0) system revealed that all the compositions investigated retained the {ital C}15-type cubic Laves phase structure. Magnetization and electrical resistivity measurements were carried out in the temperature range 77--750 K. The Curie temperature was found to increase initially from 630 K for {ital x}=0 to a value of 690 K for {ital x}=0.5 and then decrease to 130 K for {ital x}=2.0. Several anomalies observed in the resistivity measurements have been identified corresponding to spin reorientations occurring in this system. Some of these spin reorientations have also been observed in the magnetization measurements.
