Pressure effects on the electronic properties of PrAg in the ferromagnetic phase

The electronic structure of PrAg in the ferromagnetic phase has been studied as a function of pressure. The magnetic instability is analysed by calculating the total energy in the local density approximation. From the spin-polarized calculation, it is found that the magnetic moment decreases under pressure. The constant f occupation number as a function of pressure indicates that the moment reduction is not due to the f electrons' delocalization.
