Bi-layer intercalation in Bi2Se3 nanoplatelets gives rise to an intriguing crystal structure comprised of randomly stacked Bi2Se3 and Bi2Se2. Detailed conduction electron spin resonance (CESR) and AC/DC magnetization studies prove that controlling Bi intercalation results in fine tuning the two-dimensional electron gas parabolic Rashba states, which enables the appearance of extraordinary orbital magnetism, through the coupling of the spin and orbital degrees of freedom. The methodology presented herein provides a unique and simple way for efficient spin engineering, with important potential applications.
