Abstract
Improving the magneto-optical saturation signal of materials is a crucial area of research in the field of magneto-optical effect. Au@Pt nanohybrids (Au@Pt NHs) with surface plasmon resonance and spin–orbit coupling effects were fabricated using a microfluidic technique in this investigation. The Au@Pt NHs were directly dripped onto the CoFeB/W film as a deposition layer, and its dual-mode resonance was applied to increase the longitudinal saturated magneto-optical Kerr angle of the CoFeB/W film by 4.4 times. The innovative concept of using a dual-mode resonance in this paper provides a new idea for the further search of materials that have large magneto-optical coefficients.
