Schematic low-temperature phase diagram of CoCr2O4Unconventional high magnetic field phase in multiferroic material CoCr2O4

Together with colleagues from the Institute of Physics, University of Augsburg and the Institute of Applied Physics, Academy of Sciences of Moldova we have discovered a novel high-field phase in the multiferroic material CoCr2O4. This material is a possible candidate for applications.

Ein Einzeller macht es möglich: Ganz von selbst ordnen sich auf den Hüllproteinen von Sulfolobus acidocaldarius Goldatome zu magnetischen Nano-Clustern an.Strong Paramagnetism of Gold Nanoparticles Deposited on a protein Surface Layer

By means of magnetization measurements, we have observed unexpected large magnetic moments of Au nanoclusters with an average diameter of 2.6 nm which have been deposited on an organic template. This work has been done in cooperation with colleagues from Universidad de Zaragoza, the University of Granada, and the European Synchrotron Radiation Facility (ESRF) in Grenoble.

Crystal structure of Li2CuO2 with twoCuO2 chains per unit cell along the b-axis.Saturation field of frustrated chain cuprates: broad regions of predominant interchain coupling

Using high magnetic fields up to 70 T we have determined the strength of interchain coupling of frustrated chain cuprates. In cooperation with colleagues from the Leibniz Institute for Solid State and Materials Research (IFW) Dresden both an experimental and theoretical access to competing magnetic interactions in frustrated chain cuprates have been found.

H-T phase diagram of ZnCr2S4Magnetostructural Transitions in a Frustrated Magnet at High Fields

By means of ultrasound and magnetization studies in high magnetic fields we have analyzed the magnetostructural properties of bond-frustrated ZnCr2S4 spinel. These experiments made in cooperation with colleagues from the University of Augsburg provided access to the magnetic phase diagram of ZnCr2S4.
