Thermal and magnetic properties of copper potassium tutton salt below 0.15 K

Thermal and magnetic properties of copper potassium tutton salt below 0.15 K The specific heat and the ac susceptibility of copper potassium tutton salt have been measured between 0.01 and 0.15 K. The magnetic phase transition from the paramagnetic to the canted ferromagnetic state was observed at 29.5 mK in zero field. From the obtained electronic entropy curve this salt is considered to be a Heisenberg-type ferromagnet. The copper nuclear specific heat of the hyperfine splitting is estimated to beC N =1.1×10−5 R/ (T 2/[K2]), which is one order smaller than the value calculated from previous results of the paramagnetic resonance. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

The specific heat and the ac susceptibility of copper potassium tutton salt have been measured between 0.01 and 0.15 K. The magnetic phase transition from the paramagnetic to the canted ferromagnetic state was observed at 29.5 mK in zero field. From the obtained electronic entropy curve this salt is considered to be a Heisenberg-type ferromagnet. The copper nuclear specific heat of the hyperfine splitting is estimated to beC N =1.1×10−5 R/ (T 2/[K2]), which is one order smaller than the value calculated from previous results of the paramagnetic resonance.
