Abstract

Pulsed inductive microwave magnetometer (PIMM), conventional ferromagnetic resonance (FMR), and vector network analyzer FMR (VNA-FMR) have been used for complementary studies of the various excited modes in exchange-coupled NiFe(30 nm)/Ru(d(Ru))/NiFe(30 nm) films with variable Ru thicknesses d(Ru). For antiferromagnetically coupled layers, two modes, which vary in their relative intensity as a ...
