Research Abstract

Aim of the present study is to develop the system of the quasi-adiabatic specific heat measurement under high magnetic field using Coulomb Blockade thermometer (CBT) sensor, which is a primary thermometer based on the change of electric conductance of tunnel junction arrays, because the full width of the differential conductance depends only on the temperature of the sensor. The sensor can be also used as a secondary sensor by recording the amplitude at zero bias using Loch-in amplifier. This allow us to measure the temperature quick enough to perform the specific heat measurement. Installing the CBT sensor to the system, we repeated the test and improvement. Finally we could achieve the demanded level for the ordinary adiabatic method.
