Effect of pressure on magnetic properties of U(Ga sub(1-x)Sn sub(x)) sub(3) alloys

Magnetic susceptibilities, Chi , of U(Ga sub(1-x)Sn sub(x)) sub(3) alloys (with x identical with 0 and 0.45) were studied under pressures up to 2 kbar in the temperature range 64-300 K. For UGa sub(3) the pressure dependence of the Neel temperature was found to be dT sub(N)/dP identical with -1.1 pl...

Description
Summary:Magnetic susceptibilities, Chi , of U(Ga sub(1-x)Sn sub(x)) sub(3) alloys (with x identical with 0 and 0.45) were studied under pressures up to 2 kbar in the temperature range 64-300 K. For UGa sub(3) the pressure dependence of the Neel temperature was found to be dT sub(N)/dP identical with -1.1 plus or minus 0.2 K/kbar. The obtained magnetovolume effect values, dln Chi /dln V, and the results of detailed theoretical calculations of the electronic structure of UGa sub(3) for different lattice parameters have been used to evaluate the volume dependence of the effective electron-electron interaction parameter.
