About Me

Welcome! I am Dalini D. Maharaj, a teaching assistant at McMaster University and a third year PhD student in Professor Bruce Gaulin’s experimental condensed matter group. Our group conducts investigations of frustrated magnets in the pursuit of discovering exotic magnetic ground states. We utilize X-ray and inelastic neutron scattering techniques as a probe of these magnetic systems.

My primary research interests involve the study of two families of frustrated magnets – the double perovskites and rare-earth titanates of the form A2BB’O6 and A2B2O7. My thesis studies on the double perovskites involve conducting systematic investigations on a series of these materials in order to understand the role of frustration and spin-orbit coupling, in the stabilization of the novel ground states which these materials enter at sufficiently low temperatures. My work on the rare-earth titanates is focused on understanding the effect of disorder of site ions on the B site – referred to as stuffing – on the nature of the magnetic ground states in these systems. Despite having these major themes define my thesis work, my research has extended to other families of frustrated magnets through collaboration and has also included research on the high temperature cuprate superconductors.

In my free time, I enjoy hiking, trail biking and trail running and I intend on completing my first cross-country triathlon in summer 2018. Other hobbies of mine are dancing, cooking and attending music shows. I am also a beer, scotch and wine aficionado.
