Bannenberg, L.J. (author), Lefering, A.J.E. (author), Kakurai, K. (author), Onose, Y (author), Endoh, Y. (author), Tokura, Y (author), Pappas, C. (author)We present a systematic study of the ac susceptibility of the chiral magnet Fe1−xCoxSi with x=0.30 covering four orders of magnitude in frequencies from 0.1 Hz to 1 kHz, with particular emphasis to the pronounced history dependence. Characteristic relaxation times ranging from a few milliseconds to tens of seconds are observed around the...journal article 2016

(author)Small angle neutron scattering measurements on a bulk single crystal of the doped chiral magnet Fe1-xCoxSi with x=0.3 reveal a pronounced effect of the magnetic history and cooling rates on the magnetic phase diagram. The extracted phase diagrams are qualitatively different for zero and field cooling and reveal a metastable skyrmion lattice...journal article 2016

(author), van Well, A.A. (author)Nanostructuring is widely applied in both battery and hydrogen materials to improve the performance of these materials as energy carriers. Nanostructuring changes the diffusion length as well as the thermodynamics of materials. We studied the impact of nanostructuring on the hydrogenation in a model system consisting of a thin film of magnesium...journal article 2016
