The Thin Films and Interfaces Group

Progress in energy technology is closely related to the development of new functional materials. Advancing competence in the preparation and characterisation of new functional materials is therefore a strategic aim of our group. Due to its focus on application in energy technology, this research program differs from those of Materials Research Departments at other Swiss research institutions.

Coexisting multiple order parameters in single-layer LuMnO3 films
Physical Review B 94, 054423 (2016)

Magnetoelectric multiferroics hold great promise for electrical control of magnetism or magnetic control of ferroelectricity. However, single phase ferroelectric materials with a sizeable ferromagnetic magnetization are rare. Here, we demonstrate that a single-phase orthorhombic LuMnO3 thin film features coexisting magnetic and ferroelectric orders. The temperature dependence of the different order parameters are presented with ferromagnetic order appearing below 100 K and thus at much higher temperatures than ferroelectricity or antiferromagnetism (TN, TFE ≤ 40 K).
