- Abstract
- In this work, the influence of the thicknesses of ferromagnetic and antiferromagnetic layers on the magnetic properties of the synthesized Pt/Co/FeMn/Pt structure on a SiO silicon substrate was investigated. Magnetic hysteresis loops, angular dependencies of ferromagnetic resonance spectra, and the expression for the resonance field obtained by solving the Landau- Lifshitz equation for magnetization dynamics were used for experimental and theoretical studies. The coercive field values, as well as the unidirectional and uniaxial anisotropy fields, were determined for antiferromagnetic layer thicknesses of 5, 10, and 15 nm and ferromagnetic layer thicknesses of 5 and 10 nm. Suppression of uniaxial anisotropy and coercive field in the ferromagnetic layer with an increase in unidirectional anisotropy in Pt/Co/FeMn/Pt structures was observed, which is associated with enhanced exchange interaction between AFM and FM layers. The obtained results highlight the potential of using AFM/FM heterostructures in spintronic devices.
