Tóm tắt

Magnetic dynamics in superconductor (S)/ferromagnet (F)/superconductor (S) heterostructures is a focal spot in spintronics, but its physical origin remains debated. In this study, we fabricated S/F/S and S/Pt/F/Pt/S heterostructures to explore the impact of S layers on the magnetization dynamics of the F layer. We found that the ferromagnetic resonance field of the F layer shifted to lower fields as the temperature declined below the superconducting critical temperature
