(color online) in Mo (50 nm)/HM (z nm)/NM (x nm)/Fe (y nm)/NM (x nm)/HM (z nm)/Mo (50 nm) (NM = Mo, Cu, or Cr, and HM = Nd₁₆Fe₇₁B₁₃ or Pr₁₆Fe₇₁B₁₃) multilayer films at 295 K, with the applied field perpendicular to the film plane. Its dependence on (a) NM = Cu for HM = Nd₁₆Fe₇₁B₁₃ (800 nm); (b) NM = Cr for HM = Nd₁₆Fe₇₁B₁₃ (800 nm); (c) NM = Mo for Pr₁₆Fe₇₁B₁₃ (800 nm) and (d) Mo for HM = Nd₁₆Fe₇₁B₁₃ (200 nm).^[20]
