Heterometallic spin-1/2 quantum magnet under hydrostatic pressure
M. J. Coak, D. Kamenskyi, S. P. M. Curley +14
We investigate the properties of CuVOF(HO)HO, in which two different spin species, Cu(II) and V(IV), form antiferromagnetic spin-1/2 dimers with weak interdi…
Emergent Polar Metal Phase in a Van der Waals Mott Magnet
Shiyu Deng, Matthew J. Coak, Charles R. S. Haines +16
We report the emergence of a two-dimensional (2D) polar metal phase in van der Waals compound FePSe under moderate pressures. This layered material is a Mott insulator with ant…
Highly efficient nonvolatile magnetization switching and multi-level states by current in single van der Waals topological ferromagnet Fe3GeTe2
Kaixuan Zhang, Youjin Lee, Matthew J. Coak +10
Robust multi-level spin memory with the ability to write information electrically is a long-sought capability in spintronics, with great promise for applications. Here we achieve n…
Gigantic current control of coercive field and magnetic memory based on nm-thin ferromagnetic van der Waals Fe3GeTe2
Kaixuan Zhang, Seungyun Han, Youjin Lee +11
Controlling magnetic states by a small current is essential for the next-generation of energy-efficient spintronic devices. However, it invariably requires considerable energy to c…
