I am investigating the magnetic properties of the geometrically frustrated SrLn2O4 (Ln = Nd, Gd, Dy, Ho, Er) materials with a particular focus on the Nd, Gd and Er variants of the family. The effect of magnetic frustration on these systems often results in the establishment of complex magnetic structures stabilised at temperatures approaching absolute zero, spin liquids states have also been reported for a few members of the family. These materials are also know to host the magnetic ions within two slightly different crystallographic environments leading to the establishment of two types of magnetic phases in the system at low temperature. These two magnetic orders are also displaying clearly different physics when subjected to external magnetic fields.
My research activities involve sample synthesis (polycrystalline and single crystal sample preparations), sample characterisations using specific heat and magnetic susceptibility measurements but are mainly focused on performing neutron scattering experiments. Within the frame of this project, neutron scattering data have been collected on several single crystal and powder diffractometers at the ILL (D20, D2B, D7, D4, D10, D9, CYCLOPS) and ISIS (WISH) facilities giving me the opportunity to familiarise myself with instrumental techniques and to build up a strong expertise in the data analysis.
My research is performed within the frame of a scientific collaboration between the University of Warwick (supervision Dr. Oleg Petrenko) and the Institut Laue-Langevin (supervision Dr. Navid Qureshi).
