Disorder and Itinerant Magnetism in Full Heusler Pd2TiIn*

We report the electronic and magnetic properties of full Heusler Pd2TiIn based on first principles
calculations. We use general potential linearized augmented planewave method to reexamine
this issue using all electron, relativistic calculations, without shape or frozen core approximations.
We find that ideal ordered Heusler Pd2TiIn remains non-magnetic. However, we do find that it is
possible to explain the magnetism seen in some experiments through disorder and in particular we
find that site disorder can lead to moment formation in this compound. In addition, we find an
alternative low energy cubic crystal structure, which will be of interest to explore experimentally.
