Short period oscillation of the interlayer exchange coupling in the ferromagnetic regime in Co/Cu/Co(100)

摘要: A unique sample was prepared on a Cu(100) single crystal, consisting of three Co layers separated by two Cu in the form wedges oriented perpendicular to each other: Cu(100)/80 Co/Cu wedge A/30 B/30 Co/7 Cu/30 Au. Position‐sensitive magneto‐optical Kerr effect measurements along B, at fixed position corresponding maximum antiferromagnetic (AF) coupling, enabled us investigate not only AF but also ferromagnetic (F) coupling between 30 as function thickness. The confirmed both long and short period oscillations regime, revealed predicted extension through F regime.
