Effect of the magnetic field on the melting transition of H2O and D2O measured by a high resolution and supersensitive differential scanning calorimeter

Abstract

The magnetic effect on the melting transition of H 2 O and D 2 O was measured by using a high resolution and supersensitive differential scanning calorimeter working in a magnetic bore. The melting temperature of H 2 O and D 2 O at 6 T was 5.6 and 21.8 mK higher than that without the magnetic field, respectively. The temperature shifts of the melting transition of H 2 O and D 2 O were proportional to the square of the magnetic field. The temperature shifts of the melting transition due to the magnetic field did not obey the magneto-Clapeyron equation quantitatively. A dynamic effect due to the magnetic field was discussed for an alternative interpretation.
