Researchers discovered that a hidden ferromagnetic insulating (FMI) state emerged in Sr2Fe1+xRe1-xO6 films when the material’s local ionic order was disturbed by a small modification in cation ratio.1 This work provides a promising new route to developing
Researchers used neutron diffraction to map residual stress in stainless steel canisters that store spent nuclear fuel.
Concentrated transition metal alloys with the formula NiCoCrx, with x≈1, and a simple cubic crystal structure, display transport, magnetic and thermodynamic signatures exhibited by more structurally complex compounds near a quantum critical point (QCP).
Misfit heterojunctions formed by van der Waals (vdW) epitaxial growth of one crystalline metal chalcogenide monolayer on another was demonstrated for the first time to form p-n junctions that exhibit a photovoltaic response.
Thallium-doping (5%) of BaFe2As2 crystal causes a surprising rise of the antiferromagnetic transition temperature (TN), related to magneto-elastic coupling. This is the first example of the increase of TN with chemical doping in BaFe2As2.
Helium implantation allows for continuous control of optical band gaps in semiconducting films through the resultant strain — an impossibility with traditional strain engineering.
