The effect of the addition of the transitional metal Mo, on the glass-forming ability, mechanical strength and magnetic properties of Fe<SUB>78−<I>x</I></SUB>Mo<I><SUB>x</SUB></I>Ga<SUB>2</SUB>P<SUB>12</SUB>C<SUB>4</SUB>B<SUB>4</SUB> glassy alloys was investigated. The addition of 4 to 6 at%Mo was found to be effective for the extension of the supercooled liquid region (<I>ΔT</I><SUB>x</SUB>) defined by the difference between the glass transition temperature (<I>T</I><SUB>g</SUB>) and crystallization temperature (<I>T</I><SUB>x</SUB>). The <I>ΔT</I><SUB>x</SUB> value is 30 K for the Fe<SUB>78</SUB>Ga<SUB>2</SUB>P<SUB>12</SUB>C<SUB>4</SUB>B<SUB>4</SUB> alloy and increases to 60 K for the 4 at%Mo alloy. These glassy ribbon alloys exhibit good soft magnetic properties of 1.13 to 1.34 T for saturation magnetization and 2.2 to 3.8 A/m for coercive force. Based on the large <I>ΔT</I><SUB>x</SUB> values, we tried to prepare bulk glassy Fe<SUB>74</SUB>Mo<SUB>4</SUB>Ga<SUB>2</SUB>P<SUB>12</SUB>C<SUB>4</SUB>B<SUB>4</SUB> rods in a cylindrical form with different diameters. The glassy single phase was obtained in the diameter range of 1.0 to 2.0 mm. These bulk glassy alloys also exhibit high saturation magnetizations of about 1.20 T as well as a high compressive strength of 2685 MPa.
