RESUMO (em inglês)

The recent discovery of skyrmions in magnetic materials and of their self-organization into a skyrmion lattice, together with their potential for use as high density, low-energy sensors and magnetic storage has made skyrmion physics one of the hottest topics in magnetism research worldwide.

In order to increase our understanding of the physics of skyrmions and engineer them towards applications, it is essential to produce high quality materials.

In this talk, I will introduce several classes of materials which exhibit skyrmions and describe the synthesis and investigation of bulk single crystals. 

 

BREVE CV (em inglês)

Geetha Balakrishnan is a professorial research fellow in the Physics Department at the University of Warwick.

She has worked at Warwick since 1991. She has previously worked at the Tata Institute of Fundamental Research in Bombay, India (1989-1991), and as a research fellow in the Physics Department at Warwick (1986-1988).

Research interest are experimental condensed matter physics, single crystal growth and study of superconducting and exotic compounds, magnetic oxides and neutron scattering.

She is an internationally leading expert in the synthesis of single crystals of superconductors, topological insulators and magnetic materials. She oversee the crystal growth activities at Warwick.

Besides crystal growth, she has interests in neutron scattering, and allied measurements on topological insulators, superconductors, giant magneto-resistance materials and related oxides, borides and borocarbides. She has also recently had success in producing nanomaterials of the topological insulators, and in the field of skyrmionics.
