Time resolved scanning Kerr microscopy of hard disk writer structures with a multilayered yoke

Time-resolved second harmonic generation near-field scanning optical microscopy.

Novel scanning probe microscopy (SPM) spectroscopic techniques are currently receiving much attention. The increasing number of spectroscopic techniques, when combined with the high spatial resolution that is attainable with SPM, makes it possible to probe a large range of material characteristics on the nanoscopic scale. The ability to probe samples on the nanoscale with femtosecond time resol...

Bulk electronic structure of metals resolved with scanning tunneling microscopy.

We demonstrate that bulk band structure can have a strong influence in scanning tunneling microscopy measurements by resolving electronic interference patterns associated with scattering phenomena of bulk states at a metal surface and reconstructing the bulk band topology. Our data reveal that bulk information can be detected because states at the edge of the surface-projected bulk band have a ...

Benchtop time-resolved magneto-optical Kerr magnetometer.

We present here the construction and application of a compact benchtop time-resolved Kerr magnetometer to measure the magnetization precession in magnetic thin films and lithographically patterned elements. As opposed to very expensive femtosecond lasers this system is built upon a picosecond pulsed injection diode laser and electronic pulse and delay generators. The precession is triggered by ...

Time-resolved fluorescence microscopy.

In fluorescence microscopy, the fluorescence emission can be characterised not only by intensity and position, but also by lifetime, polarization and wavelength. Fluorescence lifetime imaging (FLIM) can report on photophysical events that are difficult or impossible to observe by fluorescence intensity imaging, and time-resolved fluorescence anisotropy imaging (TR-FAIM) can measure the rotation...
