Abstract
The effect of correlations and ferromagnetic order on the bulk modulus K of the 3d metals is discussed using a second order perturbation treatment of the correlation. For elements in the middle of the series with a low density of states n(EF) at the Fermi level, ferromagnetic order, if possible, acts together with correlation to reduce K. The ferromagnetic elements Fe, Co and Ni lie towards the end of the 3d series and have large values of n(EF) in the non-magnetic state. For these elements the effect of ferromagnetism on K is found to be small and may act to increase K
