Effects of high magnetic field on thermodynamic properties of pure Fe and Cu

Abstract

By the use of PPMS (Physics Property Measurement System), specific heat values of pure Cu at 2–300 K were determined under the magnetic field of 0, 3, 6 and 9 T, respectively. Magnetization curves of pure Fe under the magnetic field of 0–9 T were obtained at different temperature ranging from 5 to 300 K. Analyses of the experimental results indicate that below 300 K, magnetic fields have no effects on the specific heat values of diamagnetic Cu and very little effects on those of ferromagnetic Fe.
