WebFeb 3, 2024 · Normal paramagnetic substances obey the Curie Law. (20.10.1) χ = C T. where C is the Curie constant. Thus a plot of 1/ χ versus T should give a straight line of slope 1/C passing through the origin (0 K). Whereas many substances do give a straight line it often intercepts just a little above 0 K and these are said to obey the Curie-Weiss Law ...
