A detailed structural characterisation, by means of the powder X-ray diffraction method, of the new Pr5AgSn3 intermetallic compound has been performed and a.c., d.c. magnetic measurements in the 4-300 K temperature range and in applied magnetic fields up to 9 Tesla have been obtained and analysed, The compound orders ferromagnetically below 33.5 K and exhibits a pronounced hysteresis cycle at 5 K with a saturation magnetisation (mu(sat)) of 1.84 mu(B)/Pr atom. In the paramagnetic state the compound follows the Curie-Weiss law with mu(eff.) = 3.40 mu(B) and theta(P) = + 32 K. The splitting of the peak in the a.c. susceptibility by applied low d.c. fields as well as the temperature dependence of the remanence (B-r) and of the coercive field (H-c) are tentatively explained in terms of domain dynamics

Abstract
A detailed structural characterisation, by means of the powder X-ray diffraction method, of the new Pr5AgSn3 intermetallic compound has been performed and a.c., d.c. magnetic measurements in the 4-300 K temperature range and in applied magnetic fields up to 9 Tesla have been obtained and analysed, The compound orders ferromagnetically below 33.5 K and exhibits a pronounced hysteresis cycle at 5 K with a saturation magnetisation (mu(sat)) of 1.84 mu(B)/Pr atom. In the paramagnetic state the compound follows the Curie-Weiss law with mu(eff.) = 3.40 mu(B) and theta(P) = + 32 K. The splitting of the peak in the a.c. susceptibility by applied low d.c. fields as well as the temperature dependence of the remanence (B-r) and of the coercive field (H-c) are tentatively explained in terms of domain dynamics
