摘要：PURPOSE:To prevent the heat input and output of a thermometer and to realize accurate measurement by providing the 2nd thermal anchor made of magnetic material for measuring the temperature of the same magnetic material of adiabatic magnetization and degaussing. CONSTITUTION:Lead wires 6b and 6c between the thermometer 4 in the magnetic material 1 and the 1st thermal anchor 5 are wound around a block made of the same magnetic material in the middle to constitute the 2nd thermal anchor 11, which is fixed close to the magnetic material 1 on adiabatic basis. When the temperature of the magnetic material attains to T2 by adiabatic magnetization after the temperature of a substrate 8 and the magnetic material 1 are in a state T1, the thermal anchor 11 is at a little bit lower T2-DELTAT and the heat input value per time from the magnetic material 1 right after the adiabatic magnetization to the thermal anchor 11 is lambdaA.DELTAT, where lambda, l2, and A are the thermal conductivity, length, and sectional area of the lead wire 6c. It is difficult to extend the lead wires in order to reduce the heat input without the thermal anchor 11, but it is relatively easy to reduce the DELTAT.
