Dataset for "High resolution magnetic microscopy based on semi-encapsulated graphene Hall sensors"

The dataset contains all the characterisation and magnetic imaging data obtained in the development of a new type of nanoscale graphene Hall sensor for high resolution magnetic imaging. This has been fabricated on pre-patterned gold electrical contacts and partially encapsulated with hexagonal boron nitride to improve key figures-of-merit.

The dataset contains all the underpinning data for the manuscript entitled "High resolution magnetic microscopy based on semi-encapsulated graphene Hall sensors" published in Applied Physics Letters. This includes the characterisation data for semi-encapsulated nanoscale graphene Hall sensors as well as the results of their use to image ferrimagnetic domains in a Yttrium Iron Garnet (YIG) film. The manuscript describes the 'hot pick-up' protocol used to fabricate sensors as well as characterisation of the key figures-of merit, i.e., sensitivity and minimum detectable field. The improvement in quality due to partial encapsulation quality is demonstrated and proof-of-principle measurements made of ferrimagnetic domains in a YIG film under applied in-plane magnetic fields.

Documentation

Data collection method:

This archive contains various types of experimental research data. Atomic force microscopy images (*.ibw) were captured with a commercial Asylum microscope. Raman spectroscopy data were captured with a Renishaw inVia confocal Raman microscope. Hall voltage noise data were captured with a Nanomagnetics Instruments SPM controller and an HP 3652A Dynamic Signal Analyser. Scanning Hall probe images were captured with a Nanomagnetics Instruments scanning probe head and controller.

Data processing and preparation activities:

Scanning Hall probe images have been converted to *.txt files for easier access using the Nanomagnetics Instruments commercial software.
