 note = {Under the assumption that the change in volume of the system affects both the band width and molecular field coefficient but the shape of the density-of-states curve remains unaffected, a formula for the pressure dependence of exchange stiffness D is derived. For a system of two dimensional free electrons with step-type density-of-states curve, calculations on D and its pressure dependence dD/dp are performed with reasonable values of parameters. Calculated results well reproduce the observed composition dependence of the reduced values of D and dD/dp for fee Fe-Ni alloy system, while the calculated absolute values themselves are smaller by about an order of magnitude than the observed ones., Article, 信州大学理学部紀要 9(1): 43-53(1974)},
