Positions for PhD students:

We invite applications for a PhD-student position (fare based on german 2/3 E13 TV-L FU) in experimental solid-state physics, starting from February 1st, 2018 and limited to December 31st, 2021 within the new Collabo­rative Research Center/Transregio 227 on “Ultrafast Spin Dynamics”. (Download announcement as pdf file)

The spin dynamics in laterally magnetically inhomogeneous systems such as magnetic domain patterns and micro- or nanostructured samples is relevant for appli­cations in magnetic data processing or spin electronics. In this PhD project lateral resolution from photoelectron emission microscopy with x-ray magnetic circular or linear dichroism as contrast mechanism is used to study the lateral propagation of an ultrafast excitation of the spin system by an infrared laser pulse. An important aspect are electronic as well as magnonic spin currents resulting from the temperature gradient on the sample after laser pulse excitation and how they interact with the local spin structure of the sample, for example with magnetic domain walls.

We provide excellent conditions for motivated experimentalists. Extensive equipment and state-of-the-art surface science analysis tools can be used. While sample preparation and characterization will be carried out at the Physics department of the Freie Universität, time-resolved measurements will be conducted at synchrotron radiation sources, for example at BESSY II in Berlin.

A master's degree is required with a master thesis in experimental physics or equivalent. We are seeking a motivated candidate with team spirit and ability for independent work. Experience in one or more of the following is of advantage:  Magnetization dynamics, ultrafast pump–probe experiments, surface science, ultra-high vacuum, photoelectron microscopy (PEEM).

Postdoc positions:

Currently there are no open positions available. However, funding for postdocs from abroad may be obtained from one of several funding agencies, for instance, from the Alexander von Humboldt Foundation, or from specific funding programs for your country of residence/citizenship (see, for example, the website of KoWi, the European liaison office of the German research organisations, or search the country-specific DAAD scholarship database).
