We report on the structural and magnetic properties of newly synthesized Heusler alloys, RuFeCrSi, which have quite recently been shown to be candidates for ferromagnetic metals with high spin polarization from band structure calculations. Polycrystalline samples of Heusler alloys RuFeCrSi were prepared for 0.5≤x≤1.8. They were found to have L2 structures for 0.5≤x≤1.5 and B2 for x = 1.8. Magnetic measurements showed that they are ferromagnets. The Curie temperature for x = 1.0 was found to be 370 K. The Curie temperature tends to increase with increasing Fe concentration x. The saturation magnetic moment increases almost linearly as x increases. For higher Fe concentration the saturation magnetic moment is close to 2 μ per formula unit, which is theoretically expected.
