Dataset description

This repository contains the dataset showing the characterisation and optimisation of PMA on topological insulator epilayers conducted between the University of Leeds, Diamond Light Source and ISIS Neutron and Muon source. This is done primarily through a combination of SQUID-VSM magnetometry, PEEM and PNR measurements. Relavent PNR data can be found in the ISIS database.
