摘要	Polycrystalline samples of Gd(Co1-xMnx)(2) have been prepared by arc-melting method. The compounds form a complete solid solution with the MgCu2-type structure and the lattice constant varies monotonically as a function of the Mn content with a negative deviation from the Vegard's law. The Curie temperatures of the compounds have been determined by thermomagnetic measurements and the thermogravimetric analysis. Isothermal magnetic entropy change (vertical bar Delta S-M vertical bar) of the samples with x = 0.65, 0.7, 0.8, and 0.9 have been calculated by the magnetization isotherms. In the four samples, the addition of Mn decreases the Curie temperature, while the vertical bar Delta S-M vertical bar increases. (c) 2007 Elsevier Ltd. All rights reserved.
