Abstract
In my talk I will describe some of the cutting edge experiments that aregoing on in my research group. Our focus is the growth of thin films withatomic level control for both basic science and applications.I will focuson the area of Oxide Electronics where we are focused on a number ofimportant problems.The first will be the observation of ferromagnetism in oxides with nomagnetic dopants such as Nb or Ta doped TiO2. In both these cases,magnetic signatures were first seen by the observation of strong Kondoscattering observed in the low temperature resistivities. We confirm thatthe observed resistivity anomalies arise with a strong Kondo contributionwith a small weak localization contribution.. With further optimizationroom temperature ferromagnetism is seen in these materials. I will discussthe various experimental supporting factors besides just SQUID measurementthat give evidence for this ferromagnetism and how we rule out the effectsof artifacts, a common problem with SQUID only measurements. I will touchupon our recent efforts in the formation of Super Hydrogenic Systems, anew class of materials and give one specific example, that of Ce dopedLu2O3. Lastly but not the least I will cover some of our recentexperiments on integrating oxides with futuristic materials such asgraphene.
