摘要：

The magnetic properties of GdNi3Al16 have been investigated using both magnetic measurements in the temperature range 5-300 K and X-ray photoelectron spectroscope. GdNi3Al16 orders antiferromagnetically at T-N = 23 K. A metamagnetic transition is observed around 6 T. The magnetic susceptibility obeys Curie Weiss with mu(eff) = 8.13 mu(B) f.u. and theta(p) = -41 K. The Ni-3d band is filled and the excess magnetic moment of Gd ions is related mainly to 5d electron polarization. (C) 2002 Elsevier Science B.V. All rights reserved.
