摘要：

GdI2 is a layered d(1) compound which is isostructural with and nominally isoelectronic to the superconductors 2H-TaS2 and 2H-NbSe2. GdI2 orders ferromagnetically at 276(2) K and displays large negative magnetoresistance similar to 70% at 7 T close to room temperature. At 10 K the saturation magnetization is 7.33(5) mu(B) in good agreement with the value predicted from spin polarized band structure calculations. (C) 2000 Elsevier Science S.A. All rights reserved.
