About Prof. Aletta Prinsloo

NRF Rating: C2

Research Interest and Capability:

The Cr Research Group (CRG) focuses on the interesting magnetism observed in the arc-typical antiferromagnet Cr. Current research focuses on the physical properties of Cr-based bulk and thin film alloys. Research has further been extended to novel magnetism observed in chromite-based thin films and nanoparticles. The CRG laboratories house a state-of-the-art physical properties measurement system based on Cryogenic Limited, Cryogen Free Measurement Platform. This system can measure with the appropriate insert in a temperature range of 60 mK to close to 1000 ˚C, within a magnetic field of a few milli-Tesla up to 14 Tesla. The CRG also houses an Empyrean X-ray diffractometer capable of powder-x-ray and high resolution and gracing incidence x-ray diffraction. The x-ray diffraction instrument is also fitted with a non-ambient furnace, making it possible to study the phase behaviour of alloys in a non-reactive atmosphere.
