摘要：

The magnetic susceptibility, chi, of the itinerant antiferromagnetic compound UGa3 was studied under pressure up to 2 kbar in the temperature range 64-300 K. The measured pressure derivative of the Neel temperature is found to be dT(N)/dP = -1.1 K/kbar. In order to analyze the experimental magnetovolume effect values, d ln chi/d lnV, the volume dependent electronic structure of UGa3 has been calculated ab initio in a paramagnetic phase by employing a relativistic full-potential linear muffin tin orbital method and including an external magnetic field self-consistently. The calculations revealed a predominance of itinerant uranium f-states at the Fermi energy, as well as a large orbital contribution to chi.
