<h2 class="heading hide-accessible">Summary</h2>

This is a joint project to be carried out in collaboration between the ISIS Neutron and Muon Source, a world-leading centre for research at the STFC Rutherford Appleton Laboratory (RAL) near Oxford, and the University of Leeds. The student should spend at least one year at RAL, contributing to the development of simultaneous neutron reflectivity with optical and electrical irradiation, and the rest of their PhD in Leeds for sample growth and characterisation (including thin film and interface deposition; high-low temperature transport; magnetometry; Raman spectroscopy, He3-room temperature scanning probe microscopy etc.), device measurements and structure design. Electrical and optical stimuli make possible to manipulate the function and structural properties of advanced nanomaterials. In this studentship, we focus on the opto-electronic control of magnetic properties in hybrid organic devices &ndash; although the new beam capability may extend to applications in many other samples and structures, such as liquid crystals or solar cells. Magnets are an ever-present technological feature; from computing to energy generation. However, the production and application of these materials is reaching fundamental quantum limits while increasingly damaging the environment. Hybridisation and charge transfer between cheap, eco-friendly molecules and metals can give rise to emergent magnetic and superconducting properties. These effects are controlled by spin and electron transfer, so optical and electrical signals can tune the interfacial features. The composite devices show multifunctional properties (e.g. thermal transport, photovoltaics) that may be used in the design of molecular-scale devices; e.g. low-power consumption memories. This studentship will analyse these structures using neutron spectroscopy, adding optical and electronic capabilities to study emerging physics. The studentship has a theoretical component to study the electronic structure of these hybrids. Future applications of these developments extend to monitoring chemical, structural and mechanical changes induced by electromagnetic fields in a wide range of materials. Experience in solid state physics/electronics is highly desirable.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="https://www.leeds.ac.uk/info/130206/applying/91/applying_for_research_degrees">University&#39;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is ISIS Beamline Facility Development Studentship: Opto-Electronic Control of Magnetism as well as&nbsp;<a href="https://physicalsciences.leeds.ac.uk/staff/101/dr-oscar-cespedes">Dr Oscar Cespedes</a>&nbsp;as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a UK first class or 2:1 Masters degree in Physics or a related discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.

<h2 class="heading">Funding on offer</h2>

<p>This studentship is funded jointly by the Science and Technology Facilities Council and the University of Leeds. Funding covers the cost of fees and provides a maintenance matching the Research Council UK rate (&pound;15,009 for 2019/20). Funding duration is 3 years.</p>
