Ronny Knut came to Boulder in 2013 and worked at NIST and JILA through a Swedish grant. Beginning of 2015 he became a full time employee at JILA in the KM-group. He obtained his masters at Uppsala University in Sweden, where he also obtained his Ph.D. degree in Physics in 2012. During his graduate studies he worked on magnetic materials that are of interest for spintronics applications (TMR structures, GMR structures, half metallic Heusler alloys, magnetic semiconductors, and multiferroics). These studies were mainly performed with synchrotrons based techniques such as x-ray photoelectron spectroscopy, x-ray absorption and x-ray magnetic circular dichroism. In the KM-group he is working with the magnetics team, focusing on the study of ultrafast demagnetization in alloys, thin films and multilayers. He is also interested in the generation and applications of circularly polarized EUV and soft x-rays using higher harmonic generation, which recently has become a viable option for studying magnetic materials.
