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
Scientists have unraveled details of the mechanism of mechanical reinforcement in glassy polymer nanocomposites.1 Measurements in the interfacial layer ~2–4 nm around nanoparticles revealed that Young’s modulus, which defines the relationship between
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.
The detection of local phase transitions remains challenging, and to date most techniques can detect properties that change at macroscopic scales or at atomic scales, but virtually no technique offers the ability to monitor and map bias-induced phase trans
Giant elastic tunability—the Young’s modulus changes reversibly over 30% under applied electric fields—was discovered in BiFeO3 epitaxial thin films through an atomic force microscopy study utilizing band-excitation piezroresponse spectroscopy.
Multiferroic materials are important because their electrical and magnetic properties are coupled. Because BiFeO3 magnetically orders below 640 K, it is one of two known room-temperature multiferroic materials.
Contradicting theoretical expectations, researchers discovered that increased molecular weight of a polymer significantly reduces the influence of nanoparticles on macroscopic properties of polymer nanocomposite.
Recent developments in piezoresponse force microscopy (PFM) and spectroscopy revealed the presence of electromechanical hysteresis loops in a variety of materials including inorganic oxides, polymers and bio systems.
