摘要
Large single crystals of the title compound were synthesized from the pure elements using an excess of molten Ga as a solvent. EuGa4 crystallizes in the body-centered tetragonal space group I4/mmm (BaAl4-structure type) with unit cell parameters a = 4.407(1) Angstrom and c = 10.635(3),Angstrom, and c/a ratio of 2.413. Temperature (2-350 K) dependence of the DC magnetization, along with the temperature dependence of the electrical resistivity and electronic heat capacity, is presented. According to these measurements, EuGa4 orders antiferromagnetically near T-N = 15 K. (C) 2003 Elsevier B.V. All rights reserved.
