Lattice constants of both bcc and fcc Feo.7Nio.s alloy have been measured at high pressure by X-ray method. It is suggested that the elastic anomaly of Invar alloy is originated not only from magnitude of magnetic moment but also from its stability or stiffness of magnetic moment. The magnetic properties of transition metals and alloys (TMA) are well-known to have a large effect on the elastic constants of TMA. The magnetic contribution to the bulk modulus, B = -V x 8P/aV, of
