Quantum Phase Transitions in Ultrathin YBCO/LCMO Superlattices

ORAL

Abstract

The rational design of complex oxide heterostructures enables the investigation of novel materials with antagonistic order parameters. Our previous work has provided insight into the role of orbital reconstruction and covalent bonding at the interface of such heterostructures. In this talk, we will further address the intriguing interfacial properties and possible coupling between layers in superlattices composed of alternating superconductive YBa2Cu3O7-x and ferromagnetic La2/3Ca1/3MnO3 layers upon approaching the ultra-thin limit.
