The cover picture illustrates the Magnetic Resonance Force Microscopy (MRFM) experiments reported by E. Nazaretski et al. (p. 1758). The cantilever is equipped with the micromagnetic tip to generate the field gradient and couple to the in‐resonance spins of the sample. In the case of a ferromagnetic sample, as discussed in the paper, the inhomogeneous probe field excites highly localized ferromagnetic resonance modes. The typical MRFM signal is shown in the upper right corner. The positive contribution corresponds to the bulk‐like resonance signal similar to those observed in conventional magnetic resonance experiments. The negative part of the signal represents the tip‐induced resonance with the high degree of localization. Varying of the probe–sample distance changes the localization of the ferromagnetic resonance from hundreds of micrometers down to sub‐micron range. Two panels on the bottom demonstrate the numerically simulated lowest frequency resonance modes and their spatial confinement. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
