Are you interested in discovering how light can control magnetic ordering? As a postdoctoral researcher, you will work towards resolving how circularly-polarised phonons driven at resonance can induce ultrafast switching of magnetisation. This project is conducted at the FELIX facility and involves the development of novel laser-based experimental techniques and, subsequently, measuring how chiral phonons can ultimately drive magnetic switching.
Discovering how to control magnetisation at the highest possible speed while dissipating the least possible energy is crucial for the development of next-generation data-storage technologies. State-of-the-art theoretical proposals suggest that microscopic chiral vibrations of the lattice offer a powerful means to affect macroscopic magnetic order in a wide variety of systems. The goal of this project is to experimentally explore how magnetisation can be reversed using circularly-polarised optical phonons driven at resonance. Narrowband infrared radiation delivered by the free-electron lasers at FELIX will be used to selectively pump such phonons, either at a high repetition rate or in a single-shot fashion. In the first stage of this project, you will design, construct and optimise multi-colour pump-probe techniques capable of coherently exciting selected optical phonons and tracking in time the ensuing magnetisation dynamics. In the second stage, the novel techniques will be used to study the underlying physics of how circularly-polarised phonons govern magnetisation dynamics, identifying, for example, the speed and strength of this spin-lattice interaction.
This project will involve close collaboration with PhD candidates from the Condensed Matter Physics Group at FELIX, with the possibility to supervise both PhD projects and undergraduate/graduate internships.
- You should hold a PhD degree in Condensed Matter Physics or equivalent, with a specialisation in magnetism (or a closely related subject).
- You have an affinity for experimental physics and optics.
- Demonstrable experience using ultrafast lasers, pump-probe techniques and/or large-scale research facilities is a plus.
- You have excellent proficiency in oral and written English.
- You are enthusiastic about teamwork and collaboration with researchers (both local and from abroad).
- It concerns an employment for 0.8 - 1.0 FTE.
- The gross monthly salary amounts to a minimum of €3,226 and a maximum of €5,090 based on a 38-hour working week, depending on previous education and number of years of relevant work experience (salary scale 10 ).
- You will receive 8% holiday allowance and 8.3% end-of-year bonus.
- It concerns a temporary employment for 2 years, with an option for extension.
- You will be able to use our Dual Career and Family Care Services . Our Dual Career and Family Care Officer can assist you with family-related support, help your partner or spouse prepare for the local labour market, provide customized support in their search for employment and help your family settle in Nijmegen.
- Working for us means getting extra days off. In case of full-time employment, you can choose between 30 or 41 days of annual leave instead of the legally allotted 20.
Work and science require good employment practices. This is reflected in Radboud University's primary and secondary employment conditions . You can make arrangements for the best possible work-life balance with flexible working hours, various leave arrangements and working from home. You are also able to compose part of your employment conditions yourself, for example, exchange income for extra leave days and receive a reimbursement for your sports subscription. And of course, we offer a good pension plan. You are given plenty of room and responsibility to develop your talents and realise your ambitions. Therefore, we provide various training and development schemes.
You can apply until 20 November 2023, exclusively using the button below. Kindly address your application to Carl Davies. Please fill in the application form and attach the following documents:
- A letter of motivation.
- Your CV.
The initial closing date for applications is 20 November. However, applications will be reviewed on an ongoing basis until this vacancy is filled. The first round of interviews will take place as soon as possible after the aforementioned closing date.
You would preferably begin employment on 1 January 2024.
