Postdoctoral position in Magnetic Thin Film Multilayers with Interfacial Dzyaloshinskii-Moriya Interaction Supporting Skyrmions
Job description:For this specific project, we will design and fabricate ferro- and ferrimagnet-based thin film multilayer systems using advanced multi-source ultra-high vacuum (UHV) sputter deposition systems. The macroscopic magnetic properties of these systems will be determined using vibrating sample magnetometry (VSM). The local magnetic properties will be investigated using our home-built quantitative and high-resolution magnetic force micros-copy (MFM) systems. MFM provides sub-monolayer sensitivity for magnetic thin films and all three vector components of the stray field above the sample can be quantitatively measured with a lateral resolution down to about 10nm. The skyrmion dynamics will also be investigated by performing MFM on prototypical devices under applied current pulses.
We offer a highly stimulating research environment with an excellent infrastructure, including MFM systems that can be operated at room temperature in fields of up to 300mT, and at lower temperatures - from 5K to about 150K - in fields of up to 7T. In addition, the successful candidate will benefit from collaborations within a larger multidisciplinary international research team that will cover further experimental and theoretical aspects of this project.
Applicant's profile:We seek a candidate holding (or being close to completion of) a Ph.D. degree in experimental Physics or a closely related discipline, having a strong interest in studying novel physical phenomena at the nanoscale using unique experimental equipment. A successful applicant should have: i) a strong background and a proven record in magnetism and magnetic materials research and ii) solid knowledge and extensive experience with one or more of the following: thin-film deposition techniques, photolithography and device micro-fabrication, scanning probe microscopy (e.g. AFM, MFM, STM), VSM or SQUID magnetometry measurements. Excellent communication skills and the ability to supervise Ph.D. student lab work are expected. A good verbal and written command in English is also a requirement.
