(a) M-H loops of 120 nm diameter SAF nanoparticles with the structure of Ta 5∕Ru 2∕Co90Fe10 12∕Ru 2.5∕Co90Fe10 12∕Ru 2∕Ta 5 (in nanometers). (b) Susceptibility (normalized by the mass of Co+Fe) vs in-plane applied field demonstrating tunability of the susceptibility through interlayer magnetic interactions. The structures of the samples are listed with total thickness in nanometers: curve A (circle): Ta 5∕Ru 2∕CoFe 6∕Ru 2.5∕CoFe 6∕Ru 2∕Ta 5, total of 28.5 nm; curve B (triangle): Ta 5∕Ru 2∕CoFe 6∕Ru 0.6∕CoFe 6∕Ru 2∕Ta 5, total of 26.6 nm; and curve C (square): Ta 5∕Ru 2∕[CoFe 3∕Ru 0.6]3∕CoFe 3∕Ru 2∕Ta 5, total of 27.8 nm.
