The emergence of a new magnetic phase with a square lattice before the onset of superconductivity is revealed in some iron arsenide compounds, confirming theoretical predictions of the effects of doping on magnetic interactions between the iron atoms and their relationship to high temperature superconductivity. Understanding the origin of thermodynamic phases is vital in developing a unified theory for the elusive microscopic mechanism underlying high-temperature superconductivity.

Experiments on a copper-oxide superconductor reveal nearly static, spatially modulated magnetism. Because static magnetism and superconductivity do not like to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory. This insight will aid in writing a predictive theory for high-temperature superconductivity.

For the first time, germanium nanowires have been deposited on indium tin oxide substrate by a simple, one-step process called electrodeposition. The nanowires produced by this method have outstanding electronic properties and can be used as high-capacity anode material for lithium-ion batteries; however, the nanowires were previously too expensive and difficult to produce. This process may resolve the cost issue.

For a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition. The hybrid between a simple magnetic material and a transition-metal oxide provides a “window” to understand the metal-to-insulator transition and offers dramatic tunability of magnetic properties. Potential applications are envisioned in the fields of information storage and power transmission.
