摘要:

本文报道了一种新的金属间化合物CePd_5Al_2的电阻率、磁化率和热容的测量结果。CePd_5Al_2具有ZrNi_2Al_5型四方晶系结构,晶格参数a = 4.156 A,c = 14.883 A。该化合物具有近藤晶格行为和易平面反铁磁基态,在2.9 K和3.9 K有两个磁跃迁。索末菲系数估计为60 mJ/mol K^2。

英文摘要:

We report on the electrical resistivity, magnetic susceptibility and heat-capacity measurements on a new intermetallic compound CePd5Al2, crystallizing in the ZrNi2Al5-type tetragonal structure, with lattice parameters a = 4.156 A and c = 14.883 A. The compound presents Kondo lattice behavior and an easy-plane antiferromagnetic ground state with two magnetic transitions at 2.9 K and 3.9 K. The Sommerfeld coefficient is estimated as 60 mJ/mol K^2.
