First, sphere of Gadolinium (Gd), 0.6 mm in diameter, was prepared as a magneto-caloric medium and the temperature change of Gd versus applied field was investigated. It was found that the linear temperature rise/fall was found for applied field. Then, magnetic circuit was designed by the finite-element magnetic field analysis. The magnetic circuit consisted of NdFeB permanent magnet, iron yoke stator, and vessel for Gd sphere, with moving stage was made as a trial. A heat-exchanger circuit using coolant was constructed with water pump and solenoid and the system was tested with regard to heat-exchanging ability. The obtained temperature change was very small due to low magnetic field applied to the Gd sphere and small Gd volume. The future work was also noted.}, pages = {31--46}, title = {常温付近の磁気冷却に関する研究}, volume = {10}, year = {2005} }
