**About the Editor**

**Jacek Cwik ´** from 2018 is acting deputy branch manager of the Division of Low Temperature and Superconductivity at the Institute of Low Temperature and Structure Research, Polish Academy of Sciences, in Wroclaw. He started his scientific career in 2000 after graduating in Material Engineering at the Technical University of Wroclaw, Department for Basic Problems of Technology, in Poland. After graduation, he worked as an Assistant at the International Laboratory of High Magnetic Fields and Low Temperatures, Wroclaw. In 2006, he defended his doctoral dissertation—Institute of Inorganic Chemistry and Rare Earth Elements, Wroclaw, Poland—thesis: "Structural and physical properties of HoNi2 – MNi2 , (M = Sc, Y, La, Lu)". In 2012, he became the leader of the group at the International Laboratory of High Magnetic Fields and Low Temperatures involved in the study of materials with significant effects induced by the magnetic field. In 2016, he obtained his habilitation in Physics Sciences at the Institute of Molecular Physics, Polish Academy of Sciences, Poznan, Poland—thesis "The influence of modifying composition on magnetic and magnetocaloric properties for chosen solid solutions of Laves phase structure". Since 2017, he has been working as an Assistant Professor at the Institute of Low Temperature and Structure Research, Polish Academy of Sciences, in Wroclaw. His scientific interests are focused on the fabrication of intermetallic compounds with specific magnetic properties via the arc melting method, as well as measurements of their thermomagnetic and thermodynamic properties. He is the co-author of a unique position for direct measurements of the magnetocaloric effect using high magnetic fields generated by resistance Bitter type-magnets.
