Magnetic resonance force microscopy with a ferromagnetic tip mounted on the force detector

Magnetic resonance force microscopy with a ferromagnetic tip mounted on the force detector.

The Magnetic Resonance Force Microscope (MRFM) presents the opportunity for a magnetic resonance imaging probe with ultra-high, potentially atomic-scale, resolution. The successful application of this technique in detection of nuclear magnetic, electron-spin and ferromagnetic resonance (FMR) highlights its significant potential. We discuss the capabilities of the MRFM with particular emphasis o...

Towards a Magnetic Resonance Force Microscope Employing a Ferromagnetic Probe Mounted on the Force Detector

A crucial remaining challenge in the development of the magnetic resonance force microscope (MRFM) is to place the magnetic probe on the mechanical resonator. Here we address the problem of spurious detector response arising from interactions between the magnetic tip and various external applied elds. Ferromagnetic resonance experiments on a microscopic, thin-lm yttrium iron garnet crystal moun...

Ferromagnetic resonance force microscopy on microscopic cobalt single layer films

We report mechanical detection of ferromagnetic resonance ~FMR! signals from microscopic Co single layer thin films using a magnetic resonance force microscope ~MRFM!. Variations in the magnetic anisotropy field and the inhomogeneity of were clearly observed in the FMR spectra of microscopic Co thin films 500 and 1000 Å thick and ;403200 mm in lateral extent. This demonstrates the important pot...

Ferromagnetic resonance imaging of Co films using magnetic resonance force microscopy

Lateral one-dimensional imaging of cobalt ~Co! films by means of microscopic ferromagnetic resonance ~FMR! detected using the magnetic resonance force microscope ~MRFM! is demonstrated. A novel approach involving scanning a localized magnetic probe is shown to enable FMR imaging in spite of the broad resonance linewidth. We introduce a spatially selective local field by means of a small, magnet...
