Sam Curley will be working with Paul Goddard on an ERC project studying Quantum Materials under Extreme Conditions.
January 2017 - PhD for Joel Barker
Congratulations to Joel Barker on successfully defending his PhD thesis. Joel, whose PhD work was jointly supervised by Don Paul at Warwick and Aidy Hillier at ISIS-RAL, has been studying the physics of non-centrosymmetric superconductors with a particular emphasis on the use of muon spectroscopy.
Joel's thesis which is entitled Muon Studies of Unconventional Superconductors can be downloaded from his web page.
January 2017 - Welcome to Dr Ales Stefancic and Marta Crisanti
We welcome Dr Ales Stefancic who has recently joined the Group as Post-Doctoral Research Assistant (PDRA) studying the physics of Skyrmionic materials. Ales will work here at Warwick as part of a larger EPSRC Programme Grant Skyrmionics: From Magnetic Excitations to Functioning Low-Energy Devices involving the Universities of Durham, Cambridge, Southampton, and Oxford. The work here at Warwick will be led by Prof. Geetha Balakrishnan.
We also welcome Marta Crisanti who joins us as a Warwick/ILL Ph.D. student working under the joint supervision of Don Paul (Warwick) and Robert Cubitt who works in the Large Scale Structures Group at the ILL. Marta will also be working on Skyrmionic materials, focussing on the use of small angle neutron scattering.
Congratulations to Mo Saghir on successfully defending his PhD thesis. Mo, whose Ph.D. work was supervised by Geetha Balakrishnan, has been working on growing new topological insulators and superconductors in both bulk and nano form.
Mo's thesis is entitled Topological Insulators: A Study of Bulk Crystalline and Nanomaterials and can be downloaded from his web page.
A paper has been published in JACS which reports the accurate electron density distribution and magnetic properties of two metal–organic polymeric magnets. The work is a collaboration with the Universities of Bern, Eastern Washington, Durham, and Oxford, and the high field laboratory in Los Alamos,
The paper combines high-resolution single-crystal X-ray diffraction, DFT calculations, and magnetic studies to characterize the possible magnetic exchange pathways and establish the relationships between the electron (charge and spin) densities and the exchange-coupling constants in both compounds.
