My research is in the field of theoretical spintronics that comprises various classical and quantum phenomena related to the spin degree of freedom. In particular, recent advances in material science led to development of new materials such as complex oxides and ferromagnetic insulators with novel properties and new functionalities, often relying on the spin degree of freedom. However, understanding the behavior of these new materials quite often requires rethinking of the phenomenology by including additional interaction terms in the equations describing dynamics as well as by accounting for temperature related effects.
In addition, these new materials can exhibit new ordered phases. Phenomenological and micsroscopic theories can serve as a very useful guidelines in designing new experiments as well as in developing spintronic and magnonic devices for applications. There is a strong push in designing nanoscale devices capable of harvesting energy from temperature gradients and/or from strain. New principles of doing calculations in which the information is transferred and stored by spins might also emerge from this research.
