Strain tuning of quantum materials

16.10.2018 13:00 – 14:30

In this talk I will discuss the development of novel methods of applying uniaxial pressure to single crystals of quantum materials. Much of our work so far has been on ruthenates, but I will also mention projects on other materials. I will show that it is now possible to strain single crystals, reversibly, to change lattice parameters by at least 1%, and that this provides a ‘tuning energy scale’ equivalent to the Zeeman energy of magnetic fields of well over 1000 T. Uniaxial techniques are particularly suited to controlled tuning through Lifshitz transitions, and are also a useful complement to epitaxial strain in then films, which is usually biaxial.
