Nicholas F. Chilton

Nicholas Frederick Chilton is an Australian chemist and a Senior Lecturer in the Department of Chemistry at the University of Manchester.[1][2][3] His research is based on magnetochemistry and computational chemistry, including on the design of high-temperature single molecule magnets, design of molecular spin qubits for quantum information and in developing methods and tools for modelling magnetic calculations.[1][4]

Education

Chilton completed his Advanced Bachelor of Science (Honors) degree at Monash University in 2011 where he finished his final year project with Stuart R. Batten and Keith S. Murray.[3] He completed his PhD on magnetochemistry at the University of Manchester, supervised by Richard Winpenny and Eric McInnes in 2015.[5]

Research and career

Chilton completed postdoctoral research at the Engineering and Physical Sciences Research Council National EPR facility in collaboration with the University of Manchester. In 2016, he was awarded the British Ramsay Memorial Fellowship (2016–2018) to research how Coordination chemistry can be used to engineer specific magnetic states of lanthanide ions. From 2017, He began work as a Senior Lecturer and a Royal Society University Research Fellow in the Department of Chemistry at the University of Manchester.[3][6]

Chilton's research is generally based on computational chemistry and magnetochemistry, specifically on the design of high-temperature single molecule magnets, design of molecular spin qubits for quantum information, understanding paramagnetic MRI contrast agents, unravelling the electronic structure of uranium molecules, magnetic interactions between f-elements and in developing methods and tools for modelling magnetic calculations.[3][1][7]

Notable work

In 2017, with David P. Mills, Chilton led research on the magnetic hysteresis at 60 Kelvin in dysprosocenium.[8] This was the first time a higher temperature magnetic hysteresis had been observed, with the previous record being 30 K.[9] The research introduced the ability to use liquid nitrogen instead of more expensive liquid helium during the magnetic hysteresis phenomenon which led to the attention of data storage server companies as the research introduced the potential of reducing both costs and energy requirements of data servers.[10]

Chilton has also collaborated in developing software to be used in chemical research.[11] In 2013, with Alessandro Soncini he designed a computer program for the determination of the orientation of the magnetic anisotropy of the mJ = ±15/2 state of DyIII via electrostatic optimation of the aspherical electron density distribution.[12] He also designed a program named PHI for the calculation of the magnetic properties of paramagnetic coordination complexes in the same year [13] and in 2019, with Daniel Reta, designed CC-FIT2, a tool for the fitting of experimental AC magnetic data using the (generalised) Debye model, extraction of magnetic relaxation times with associated uncertainties, and fitting the temperature dependence of these data accosting for uncertainties in the underlying relaxation times [14]
