Biography

 Prof Moise Tchokonte is an Associate Professor in the Department of Physics. He obtained his DEA in Theoretical Physics at the University of Yaounde, Cameroon, his MSc degree in Theoretical Physics and his PhD degree in experimental condensed matter Physics at Wits University.
Prof Tchokonte received two awards at the South African Institute of Physics conferences: one award for the most outstanding poster presentation in the field of Solid State Physics and / or Materials Science delivered at the Annual South Africa Institute of Physics Conference in Potchefstroom, 2002. The second award was for the most outstanding work in the field of Solid State Physics and / or Materials Science based on a publication in a Scientific Journal originating from his Doctoral Thesis, at the Annual South Africa Institute of Physics Conference in Stellenbosch, 2003. He is a Member of the South African Institute of Physics and a Regular Associate of the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy.

His activities are based on Experimental research in the Strongly Correlated Electron Systems, or magnetism in the solid state and condensed matter Physics. He has made very interesting and generated exhaustive work on the competition between the Kondo effects and magnetic inter site interaction in alloys with Cerium. His research field of strongly correlated electron systems: Transport and magnetic properties of heavy-fermion and Kondo Cerium compounds. His research on these compounds involves measurements, analysis and interpretation of transport and thermodynamic properties such as electrical resistivity, magnetoresistivity, thermoelectric power, magnetic susceptibility, magnetization and specific heat capacity over a broad range of temperature and magnetic fields. He recently set up a closed – cycle Helium refrigerator for electrical resistivity measurements from room temperature (300 K) down to 2.5 K in his research laboratory. He has published several research papers in Peer-reviewed research journals and presented his research findings and interpretations at several national and international conferences and workshops.
