Quantum Materials

The properties of a large class of materials are determined by quantum effects. In such quantum materials, interesting novel phases emerge due to a subtle interplay between different microscopic degrees of freedom.

Like magnetism and superconductivity, those quantum phases are not only of high interest from the fundamental science perspective, but also have potential applications in quantum science and technology. We fabricate thin film and multilayer quantum materials, including magnetically ordered insulators (e.g. Y3Fe5O12 or α-Fe2O3), spin-orbit driven materials (e.g. Sr2IrO4), or Dzyaloshinskii-Moriya-active interfaces...
