The sputtering rate of Pt, Au, Fe and Co targets was researched and they were 0.059 nm/s, 0.076 nm/s, 0.050 nm/s, and 0.030nm/s respectively. A series of magnetic multilayers were prepared using the calibrated rate and the anomalous hall effect of the samples were tested, and Hall curve was in line with expectations. The sputtering rate of Pt, Au, Fe and Co targets was appropriate for sample preparation. Suitable sputtering rate play a decisive role in sample preparation.

An analytic method is proposed to calculate the formation enthalpy directly from empirical n-body potential and applied to the binary and ternary systems consisting of the refractory metals Mo, Nb, Ta and W. It turns out that the calculated enthalpies are in overall agreement with experimental observations and some other theoretical calculations. Interestingly, it shows that the formation enthalpies of the ternary systems are significantly affected by those of the constituent binary systems.
