Atomic control of magnetism in oxide heterostructures & Ferroelectric order in high-Tc superconductors

- In the first part of the talk I will discuss our recent demonstration to control both the strength and the direction of the interfacial magnetism over a broad range in oxide heterostructures. Such high degree of tunability promises structures and devices with magnetic and mechano-magnetic properties controllable at the atomic monolayer level.

- In the second part of the talk, I will focus on the discovery of a ferroelectric ground state in underdoped high temperature superconductors due to charge carrier-doping. The results demonstrate that charge ordering associated with ferroelectricity is the mechanism for symmetry breakage in underdoped cuprates.
