Magnetic properties of amorphous Co₀.₇₄Si₀.₂₆/Si multilayers with different number of periods
Two sets of [Co₀.₇₄Si₀.₂₆0.26(5 nm)/Si(s)]n amorphous films were prepared by magnetron sputtering: one in the form of multilayers with the Si spacer thickness s fixed at 3 nm, and the number of periods n varying from 1 to 10; and another one with only two periods and s varying from 3 to 24 nm (trila...
