Nano-sized SQUID-on-tip for scanning probe microscopy

Scanning hall probe microscopy technique for investigation of magnetic properties

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

Nano-structuring with laser illuminated scanning probe tip array

Nano-structuring of various materials is important for a number of future oriented technical applications. Local intensity enhancement of laser irradiation in the near field of a SPM tip enables the processing of sub-diffraction limit features. The tip-sample gap, which is a critical parameter for the field enhancement needs to be very precisely controlled. In the present work, the design of la...

Scanning Squid Microscopy

The scanning SQUID microscope (SSM) is a powerful tool for imaging magnetic fields above sample surfaces. It has the advantage of high sensitivity and bandwidth and the disadvantages of relatively modest spatial resolution and the requirement of a cooled SQUID sensor. We describe the various implementations of this type of instrument and discuss a number of applications, including magnetic imag...
