The Laboratory for Mesoscopic Systems based at the Paul Scherrer Institute (PSI) is a joint laboratory between the ETH Zurich and the Paul Scherrer Institute, which is the largest research centre for the natural and engineering sciences in Switzerland. The current research focus is the investigation of novel magnetic systems at the mesoscopic scale making use of the clean rooms and large-scale facilities at the Paul Scherrer Institute, and fostering the synergies with the Department of Materials (ETH Zurich). We would like to hire a Postdoctoral Researcher in the field of Ultrafast Magnetism and Nanomagnetic Materials.
Project background
Magnetic materials are important for several real-world applications including motors, actuators, sensors and computation. For example, heat-assisted magnetic recording is a breakthrough technology that integrates a tiny laser and nanoantenna directly into hard drives, pushing the limits of data storage density and paving the way for the next generation of ultra-high-capacity devices. In the endeavor to make faster and more energy efficient materials, we will manufacture arrays of interacting nanomagnets (so-called artificial spin ice) and determine their interaction with ultrashort (1e-13 s) laser pulses. Preliminary experiments have already revealed an unexpectedly fast magnetic response, sparking our interest to explore deeper and uncover the mechanisms behind these intriguing phenomena. Such a quest will involve fabricating new samples, performing experiments with our femtosecond laser, and leveraging novel X-ray laser facilities such as SwissFEL. Exploring these effects at a fundamental level will not only deepen our understanding of magnetization dynamics, but also lay the groundwork for future applications in energy-efficient technologies.
Job description
You will lead a project focused on performing femtosecond laser measurements on arrays of coupled nanomagnets. In addition, you will contribute to the conception and design of cutting-edge experiments at X-ray free-electron laser (XFEL) facilities. The role will also involve sample preparation, and characterization using both standard lab-based methods (optical and scanning electron microscopy, magnetometry, Kerr microscopy) and advanced synchrotron X-ray techniques at the Swiss Light Source and other international synchrotron X-ray facilities. This position offers the opportunity to combine ultrafast laser science, nanofabrication, and large-scale facility experiments to advance our understanding of emergent magnetic phenomena.
Profile
You have outstanding qualifications with a PhD in physics, materials science, or a related discipline, and a strong background in magnetism. Experience with sample preparation methods, such as nanofabrication using electron-beam lithography, is highly desirable. Familiarity with ultrafast laser experiments or synchrotron / XFEL facilities will be considered a strong asset. You should be enthusiastic about combining hands-on experimental work with conceptual thinking, and capable of working both independently and as part of a collaborative, international team.
We offer
You will work in Mesoscopic Systems joint laboratory between the Department of Materials, ETH Zurich and Paul Scherrer Institute. ETH Zurich is one of the world's leading universities specialising in science and technology. We are renowned for our excellent education, cutting-edge fundamental research and direct transfer of new knowledge into society.
