 His explanation of nonlinear effects in ferromagnetic resonance in known as the Suhl instability, and one of the major sources of broadening of nuclear magnetic resonance lines in magnetically ordered media is known as the Suhl-Nakamura interaction.A particular divergence in the calculated properties of dilute magnetic alloys is known as the Abrikosov-Suhl resonance.Suhl was a member of the National Academy of Sciences and a Fellow of the American Physical Society.
