An in-situ Strain Manipulation Stage
ORAL
Abstract
Complex transition metal oxides, because of their correlated d electrons, feature a rich phase diagram of interplay between spin, charge, and orbital degrees of freedom. It has been demonstrated that strain engineering is a powerful tool in the exploration of this phase diagram. However, the strain achievable by existing techniques is limited to either discrete/small [1][2] values or specific symmetries/directions [3][4]. Recent advances in strain tuning capabilities of freestanding oxide membranes have demonstrated the potential in realizing continuous control of strain in arbitrary symmetries [5][6]. In this work, we report our recent development of an in-situ mechanical manipulation stage and illustrate its capabilities with preliminary results of tuning prototypical oxides.
