| 英文摘要 | The detailed studies of magnetic properties and resistivity in the ternary intermetallic compound TbFe2Ge2 are preset. Besides the how temperature antiferromagentic transition at TN=8.5K, the second anomaly in magnetic and electric properties have been found at about Tsc=250K. Below TN, a metamagnetic behavior was observed. In the region TN<T<Tsc, the magnetic susceptibility and magnetization data show that an extra spin magnetic moment appears, in addition to the Curie-Weiss and Pauli paramagetism. It is suggested that the observed anomalies in the temperature dependencies of resistivity and magnetic susceptibility are related to an effect of spin correlations. Several mechanisms of the spin fluctuations are discussed. |
