In order to extend the field range (0 – 30 T) of the data measured at HFML-Nijmegen, I performed magnetotransport measurements on an ionic-liquid gated two-dimensional electron gas (2DEG) at complex oxides interface in pulsed magnetic fields up to 60 T and at temperatures down to 350 mK at LNCMI-Toulouse. These complementary data will certainly help to better understand the complex quantumoscillation spectra in the 2DEG at oxide interfaces. Apart from the measurements, I had the opportunity to discuss the obtained results and strategies for common publications with the LNCMI team, including Dr. Walter Escoffier and Prof. Michel Goiran, as well as with Dr. Ariando from the National University of Singapore. Since I worked as a postdoctoral researcher at LNCMI-Toulouse in 2018, the EMFL exchange program gave me the excellent opportunity to utilize my pulsed-field expertise and to deepen the ongoing collaboration with my former colleagues.
From the technical point of view, it has been a great and unique experience to perform electrical-transport experiments in both pulsed and DC field facilities since these installations involve different equipment, such as dedicated probes, sample holders, and electrical devices for the measurements. My exchange visit contributed meaningfully to an optimization of future combined magnetotransport measurements in pulsed and continuous magnetic fields. As an immediate result of my work, we submitted an EMFL magnet-time proposal to HMFL Nijmegen.
