Scaled Equation of State and Critical Exponents in Magnets and Fluids

A systematic analysis in the context of the scaled equation of state has been made of available experimental data in the critical region of a number of ferromagnets [Gd, Cr${\mathrm{Br}}_{3}$, ${\mathrm{La}}_{0.5}$${\mathrm{Sr}}_{0.5}$Co${\mathrm{O}}_{3}$, Ni (two independent sets of data)] and fluids (C${\mathrm{O}}_{2}$, ${\mathrm{He}}^{4}$, Xe) with the following assumed form for $h(x)=H{M}^{\e…
