Split‐ring resonators with a magnetic resonance in the near‐infrared have been fabricated using the rapid‐ prototyping capabilities of focused‐ ion‐beam writing. By varying the design parameters, a continuous transition from a degenerate Mie resonance to a magnetic‐dipole response is shown (see Figure). In particular, a negative magnetic permeability at a wavelength of 2.4 μm and a negative magnetic susceptibility at a wavelength of 1.7 μm are demonstrated.
