How to find the sputtering power and time of sputtering of individual targets to make a desired alloy composition using co-sputtering technique?

I have two different sputtering targets (A and B) mounted at 45 degree incident angle. I have already found their individual deposition rate (Ang/secs) at different power. Deposition rate...

What is the difference between the detection scheme for a FMR(ferromagnetic resonance) and EPR(Electron paramagnetic resonance) signal?

FMR signal can only be identified significantly, if the hrf(Magnetic field component) of RF wave is orthogonal to the external magnetic field applied. Is it also necessary with EPR detection? If...
