摘要：

The magnetizations, magnetic susceptibilities, and specific heats of both stoichiometric and nonstoichiometric single crystals GdAs are measured at temperatures 1.7 less than or equal to T less than or equal to 300 K and magnetic fields 0 less than or equal to H less than or equal to 24 T. A systematic comparison between the magnetic behavior of the stoichiometric and nonstoichiometric samples is carried out. The stoichiometric sample shows the magnetic features expected for a Heisenberg antiferromagnet. For the nonstoichiometric sample, some anomalous magnetic properties are observed and explained by the trapped magnetic polaron model.
