A sample of the paramagnetic salt to which the magnetization curve of Fig. 32-14 applies is to be tested to see whether it obeys Curie\"s law. The sample is placed in a uniform 0.50 T magnetic field that remains constant throughout the experiment. The magnetization M is then measured at temperatures ranging from 10 to 300 K. Will it be found that Curie\"s law is valid under these conditions?

 

Fig. 32-14 A magnetization curve for potassium chromium sulfate, a paramagnetic salt. The ratio of magnetization M of the salt to the maximum possible magnetization M_max is plotted versus the ratio of the applied magnetic field magnitude B_ext, to the temperature T. Curie\"s law fits the data at the left; quantum theory fits all the data. After W. E. Henry.
