Abstract
The low temperature heat capacity and magnetization were measured for the P r,Co,Al, intermetallic compound. A ferromagnetic transition was observed at 4.5 K with a saturation value of the magnetic moment of the Pr atom in the ordered state of 1.1 mu(B) at 2.5 K. In the paramagnetic region the compou nd follows the Curie-Weiss law with mu(eff) = 3.59 mu(B) and theta(P) = +5 K. Above the magnetic transition an estimate of the electronic coefficient of the specific heat was obtained. (C) 1999 Elsevier Science S.A. All right s reserved.
