%X We report frequency dependent (f = 0.1 to 5 MHz) electrical resistivity in Sm0.1La0.6Sr0.3MnO3 in superimposed dc magnetic fields (H = 0每1 kOe). Resistive (老∩) and reactive (老∪) components of the complex resistivity (老 = 老∩+i老∪) were measured simultaneously. With increasing f, both 老∩ and 老∩∩ increase abruptly at the onset of ferromagnetic transition (Tc = 348 K) and exhibit an anomaly at T *＞ 147 K   Tc in H = 0 kOe. The observed features in 老∩ and 老∩∩ are depressed with increasing H leading to 35% magnetoresistance for 忖H = 300 Oe and f = 3 MHz. It is suggested that the frequency dependent magnetotransport is dominated by the field and frequency dependences of the ac permeability.
