N2 - The magnetizations, magnetic susceptibilities, and specific heats of both stoichiometric and nonstoichiometric single crystals GdAs are measured at temperatures 1.7≤T≤300 K and magnetic fields 0≤H≤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.
