Serkan Akansel: Early Stage Researcher

I received my bachelor degree on physics engineering from Hacettepe University, Turkey, where I also received my MSc. degree in nanotechnology and nanomedicine. During my masters, my main interest was synthesis and characterization of complex hydride nanoparticles which are useful for solid state hydrogen storage. In addition to this topic I was also involved in a project aiming shape and size controlled synthesis and characterization of FePt nanoparticles which have possible application field in magnetic memory applications.

After my MSc. I joined Prof.Peter Svedlindh’s group at Uppsala University in Sweden as a PhD. student. My main research interest during my PhD. studies is magnetization dynamics of thin films which could be promising materials for future spintronic devices and as well as magnetic memory applications including magnetic random access memories. I mainly characterize both static magnetic properties of films by using vibrating sample magnetometer(VSM) or squid equipment and dynamic properties by either broadband ferromagnetic resonance (FMR) or cavity FMR techniques.

During my PhD. studies I visited Seagate Technology as a Marie Curie Early Stage Researcher on the NU-MATHIMO project. This visit gave me a chance to utilize my academic background while working in an industrial environment. I had a chance to work in a clean room and deposited thin films with industrial scale equipment. In addition to film preparation I carried out characterization measurements via looper setup in order to get static magnetic properties of the films and X-ray fluorescence(XRF) measurement for composition and thickness characterization.

My main interest was FeCo thin film alloys during my secondment period. These materials are quite promising for magnetic read head applications on hard drives with their high saturation magnetization. However they have a drawback such as their ability to switch. I prepared these films with different seed layers which improved their ability to switch magnestisation. These films are also characterized in terms of damping parameter in my group at Uppsala University . In addition to adding seed layers, these FeCo thin films are also doped with 5d elements in order to obtain high damping. Theoretical calculations of this study is done by Biplab Sanyal’s group at Uppsala and FMR measurements are with our broadband FMR setup in Uppsala as well.

This secondment was quite a helpful experience for me for my future career since now I had an idea of how industrial companies work and how I can use my academic skills in a company which is producing state of art technologies.
