Laves相稀土-过渡族金属间化合物Tb1-x DyxCo1.95的磁学性质及相变研究
Study on Magnetic Properties and the Nature of Phase Transition of Laves Phase Rare Earth-Transition Metal Compounds Tb1-xDyxCo1.95
摘要
Abstract
The magnetic properties and the nature of phase transition properties of Tb1-xDyx Co]95 was studied in this work,which was belong to the rare earth-transition intermetallic compounds system.The structure of compounds was test by the X-ray diffractometer.The magnetic properties and the types and temperatures of magnetic phase transitions were measured by the magnetic property measurement system,and the thermal expansion curves were test by the thermomechanical analyzer.The results show that the lattice constant and Curie temperature of the material tend to decrease with the increase of the content of Dy element in the system.The first-order phase transition properties of compounds can be derived from more in-depth data analysis,which fills the research gap in related fields.In addition,the energy change of the Tb1-xDyxCo1.95 system when the magnetic phase transition occurred compensated for the normal ther-mal expansion and contraction,which resulted in a small thermal expansion effect in the Tb1-xDyxCo1.95 system within a certain temperature range.关键词
