About Prof. Andr茅 Strydom

Primary Expertise: Physics of highly correlated matter

Secondary Expertise: Magnetism of 4f-electron systems, low-temperature charge and spin ordering phenomena, ground states of matter

NRF Rating: B2 (Internationally acclaimed researcher)

Experimental Facilities

A suite of electronic transport, thermal transport, thermodynamic, magnetic, and dilatometry measurement options are made possible by three experimental stations housed in the Laboratory of our Highly Correlated Matter Research Group in the Physics Department. We have at our disposal facilities to achieve experimental temperatures between 0.05 K and 400 Kelvin, and in applied magnetic fields of up to 9 Tesla. We have various sample synthesis facilities for direct melting of reactant materials and controlled high-temperature reactions.
