N2 - In general, the intensity of magnetization, M, is dependent on both magnetic field, H, and on time and may be described in terms of a constitutive equation, or equation of state as dH = (1/χ)dM + Λd In M, where 1/χ = π{variant}H/π{variant}M{norm of matrix}Ṁ and Λ = π{variant}H/π{variant} In Ṁ{norm of matrix}M. Measurements have been made on Pr15Fe77B8 from which values of Λ and χ as functions of M are derived using the constitutive equation. It is shown that χ is a function of M but is independent of Ṁ. At room temperature Λ = (86.0±1.4) Oe over the magnetization range + 300 to -500 G.
