Yunbo Ou, Murod Mirzhalilov, Norbert M. Nemes +20
Exchange-coupled interfaces are pivotal in exploiting two-dimensional (2D) ferromagnetism. Due to the extraordinary correlations among charge, spin, orbital and lattice degrees of…
The effect of surface oxidation and crystal thickness on magnetic properties and magnetic domain structures of Cr2Ge2Te6
Joachim Dahl Thomsen, Myung-Geun Han, Aubrey Penn +10
Van der Waals (vdW) magnetic materials such as Cr2Ge2Te6 (CGT) show promise for novel memory and logic applications. This is due to their broadly tunable magnetic properties and th…
Salt-assisted vapor-liquid-solid growth of one-dimensional van der Waals materials
Thang Pham, Kate Reidy, Joachim D. Thomsen +4
We have combined the benefits of two catalytic growth phenomena to form nanostructures of transition metal trichalcogenides (TMTs), materials that are challenging to grow in a nano…
Probing defects and spin-phonon coupling in CrSBr via resonant Raman scattering
