We report the first demonstration of an optical "magnetic mirror", i.e. mirror that in contrast to a conventional mirror inflicts only a small or zero change to the phase of a reflected wave. Magnetic mirror property was observed in a nanoscale version of a novel "magnetic wall" metamaterial that has recently been proposed for microwave applications [Appl. Phys. Lett. 88, 091119 (2006)]. The essential component of the optical magnetic mirror, a nanostructured metal film patterned as fish was fabricated using electron beam lithography. We measured spectral dependence of the phase shift acquired by the wave reflected from the magnetic mirror in the 550-1750 nm spectral range and found a strong resonant reduction of the phase shift at wavelengths around 650 nm. Our experimental data are consistent with the results of the corresponding numerical simulation based on the method of moments and finite element solution of the Maxwell equations.
