Introduction

Publications

Assistant at the Faculty of Mathematics and Physics of the University of Ljubljana. Research performed within employment at the Faculty of Mathematics and Physics and also via employment at the Jožef Stefan Institute.

Office hours for students according to prior arrangement. Prefer to be contacted via the email primoz.kozelj@fmf.uni-lj.si.

Winter semester of 2021/2022: Excercise class in Physics 2 for students of "Techniques of measurement in physics". Course information available (in Slovene only) at FMF Online classroom.

Interested in experimental solid state physics, especially physics of metals and other materials. My main research methods include magnetic measurements, electrical resistivity, specific heat and thermal transport measurements both above room temperature and all the way down to cryogenic temperatures.
From 2014 until now my main focus have been the physical properties of high-entropy alloys. Two particular interests of mine are superconductivity and magnetism in high-entropy alloys. See list of publications and also our group web page at http://slo-hea.ijs.si/.
During my postdoc at the Max Planck Institute for Chemical Physics of Solids in Dresden, Germany (Department of Prof. Dr. Juri Grin, REALM group of dr. Eteri Svanidze) I was working also on lanthanide and actinide materials.
