"The project consists of an extensive research on the control of the macroscopic magnetic properties by means of electric fields in nanostructures based on the so far unexplored I-II-V classof room temperature semiconductors. We aim coupling LiMnAs to soft ferromagnets by exchange bias and tune this exchange bias using epitaxial strain and electrical gating. To keep the compatibility with current semiconductor growth industry, films and nanostructures will be grown and patterned on substrates such as GaAsor InAs. Owing to its novelty, the picture of the crystal and magnetic structure in strained epitaxial LiMnAs films is lacking. We propose to study the materials by means of laboratory and x-ray synchrotron radiation sources complemented with neutron diffraction. The goal of the project is to deliver a comprehensive characterization of nanostructured LiMnAs materials in which the magnetic order can be controlled by electric fields at room temperature."@en .
