The research in Strongly Correlated Materials Lab (SCML) is focused on discovery of novel magnetic phases and magnetic matter in complex oxides and intermetallics. We perform fundamental experimental work on frustrated magnetism and multiferroics. SCML houses an optical floating zone furnace and an X-ray Laue camera for the crystal growth of complex oxides and their crystallographic orientation, respectively. We travel to the X ray and neutron national laboratories in the country to perform advanced experiments on the crystals that we prepare at Â鶹¹ÙÍø.
