The ferromagnetic resonance studies were carried out at room temperature on fine powders of Ho{sub 0.85}Tb{sub 0.15}Fe{sub 2}H{sub {ital x}} ({ital x}=0--3.1) and Dy{sub 0.73}Tb{sub 0.27}Fe{sub 2}H{sub {ital x}} ({ital x}=0--3.3) at {ital X} and {ital Q} bands. The {ital g} values were found to decrease with increasing hydrogen concentration in both the systems. This data along with the earlier magnetization and Moessbauer data have been used to explain the observance of {ital T}{sub comp} in the hydrogenated samples of Ho{sub 0.85}Tb{sub 0.15}Fe{sub 2}.
