摘要
We have developed a differential scanning calorimeter capable of working under applied magnetic fields of up to 5 T. The calorimeter is highly sensitive and operates over the temperature range 10-300 K. It is shown that, after a proper calibration, the system enables determination of the latent heat and entropy changes in first-order solid-solid phase transitions. The system is particularly useful for investigating materials that exhibit the giant magnetocaloric effect arising from a magnetostructural phase transition. Data for Gd-5(Si0.1Ge0.9)(4) are presented. (C) 2003 American Institute of Physics.
