In detail, single crystal WSe₂ is codoped with 4 at% Co and various concentrations of Nb by employing the physical ion implantation method. Raman, X-ray diffraction and X-ray photoelectron spectroscopy results reveal the effective substitutional doping of implanted elements (Co and Nb). Magnetic measurements illustrate that both un-doped and 4 at% Co doped WSe₂ show weak ferromagnetism whereas magnetization is strongly enhanced when Co and Nb are codoped into WSe₂. The magnetization is comparable with a ferromagnet, which may be attributed to Co, Nb doping and defects. In addition, a large coercivity of ≈1.2 kOe is observed in the 1 at% Nb–4 at% Co codoped WSe₂ sample, which may be ascribed to the combined effect of doping-induced stress, defect-dictated pinning and anisotropy of Nb-Se bond owing to the charge transfer between Nb and Se ions.]]> Tue 05 Jul 2022 11:09:36 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49938 Thu 15 Jun 2023 16:14:47 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31820 6 measurements per week, and makes scalable distributed routing decisions.

With the increase of the protons intercalated among vdW layers, interlayer magnetic coupling increases. Because of the existence of antiferromagnetic layers in FGT nanoflakes, the increasing interlayer magnetic coupling induces exchange bias in protonated FGT nanoflakes. Most strikingly, a rarely seen zero-field cooled (ZFC) exchange bias with very large values (maximally up to 1.2 kOe) has been observed when higher positive voltages (V_g ≥ 4.36  V) are applied to the protonic gate, which clearly demonstrates that a strong interlayer coupling is realized by proton intercalation. Such strong interlayer coupling will enable a wider range of applications for vdW magnets.]]> Fri 01 Jul 2022 10:33:31 AEST ]]>
