%X The amorphous (Fe<sub>1-x</sub>Mn<sub>x</sub>)<sub>75</sub>P<sub>15</sub>C<sub>10</sub> (0 ¡Ü x ¡Ý 0.30) alloys were prepared by the standard melt spinning technique and investigated their crystallization, thermal, transport and magnetic properties. Crystallization was observed from 400¡æ to 650¡æ with an interval 50¡æwithin 30 minutes annealing time by XRD. The as-cast samples were amorphous in nature. Annealing 400¡æ to 450¡æ samples showed the mixed bcc Fe and amorphous structures. The lattice parameter ¡®a¡¯ was varied from 2.855 to 2.859 ? but above 450¡æ, samples contained hexagonal, FeP and FeC structures. The lattice parameters ¡®a¡¯ and ¡®c¡¯ were varied from (5.016-5.036) ?  and (13.575-13.820) ? , respectively. Average crystallite size was found to vary from 8 to 48 nm. Crystallization temperature and weight change were observed by differential thermal analysis and thermogravimetric analysis, respectively. Crystallization temperature was increased with increasing Mn content. Resistivity was increased above and bellows the Curie temperature. Real permeability remained almost constant upto around 10<sup>6</sup> Hz for of all samples after that it was decreased with increasing frequency and it was also decreased with Mn, whereas imaginary permeability was increased sharply above frequency 10<sup>7</sup> Hz. The value of saturation magnetization was found to decrease with increment Mn.
