PhD Thesis Defense: "Preparation and characterization of biferroic nanostructures with magneto-electric coupling" by Nico Dix on 27 April at 11:30 am

The PhD Student Nico Dix, from the Multifunctional Thin Films and Complex Structures (MULFOX) group will defend his PhD thesis:

Title: Preparation and characterization of biferroic nanostructures with magneto-electric coupling

Date:  Thursday 27 April

Time: 11:30 am

Place: Sala d'Actes Carles Miravitlles (ICMAB)

Complex oxides present a broad spectrum of functional properties, materials with a coexistence of ferroelectric and ferromagnetic order, and coupling between this ferroic orders could lead to large magneto-electric responses. Here we present our study on artificial two phase magnetoelectric composites composed of ferroelectric (BaTiO3 and BiFeO3) and ferromagnetic (CoFe2O4) phases, exploring potential strain mediated magnetoelectric coupling above room temperature.
We investigated two distinct nanocomposite geometries; (1) layered horizontal heterostructures (BaTiO3/CoFe2O4) and (2) self-organized column-matrix heterostructures (BiFeO3/CoFe2O4 and BaTiO3/CoFe2O4). Epitaxial growth using pulsed laser deposition (with in-situ electron diffraction) and rf sputtering was achieved for each case, and the structure, morfology and physical properties were analysed in detail. The composites are biferroic at room temperature and show magnetoelectric coupling.
