Background and activities
I study how magnetism can be controlled in complex oxide materials. In particular, I investigate the possibility to tailor the properties of ferro- and antiferromagnets by thin film epitaxy and nanopatterning. Currently, I explore the use of domain engineered nanomagnets in novel ultra-low energy magnetic logic.
Working with research questions at the intersection of physics, material science, and computer science, I collaborate with research groups in Norway, Belgium, USA, United Kingdom, and Switzerland. I am also an active user on several synchrotron facilities (ALS, SLS, BESSY).
- Domain engineering in complex oxides
- Antiferromagnetic spintronics
- Nanomagnetic logic (NML)
- Artificial Spin Ice
- Magnetic domain imaging (X-PEEM, MFM, STXM)
- Nanofabrication (EBL, FIB, Ion patterning)
- TFE4146 Semiconductor Devices
- TFE4172 Introduction to Semiconductor Devices
