Researchers have demonstrated a novel way to systematically strain-engineer oxygen vacancies in complex transition-metal oxide thin films. The work advances our ability to tailor such defects, small changes in which can lead to dramatic changes in material properties such as conductivity and magnetism. ... Read more »
Magnetism Emerges at Wonky Interfaces
Researchers have found a new way to control magnetism at the atomic level that will serve as a model for studying emergent phenomena in other systems. The ability to engineer and tune properties on such small length scales can (eventually) enable us to design exciting new magnetic devices. ... Read more »
New Multiferroic Material for Ultralow-Power Electronics
Scientists paired ferroelectric and ferrimagnetic materials so that their alignment can be controlled with a small electric field at near room temperatures, a major step in the development of ultralow-power microprocessors, storage devices, and next-generation electronics.

3D Charge Order Found in Superconductor
Resonant soft x-ray diffraction studies of a cuprate high-temperature superconductor revealed a 3D, long-range charge order—the first of its kind ever reported in a cuprate—that competes with superconductivity. A better understanding of such phenomena could help in the design of more robust superconductors with higher transition temperatures.

IBM Probes Material Capabilities at the ALS
Vanadium dioxide, one of the few known materials that acts like an insulator at low temperatures but like a metal at warmer temperatures, is a somewhat futuristic material that could yield faster and much more energy-efficient electronic devices. Researchers from IBM’s forward-thinking Spintronic Science and Applications Center (SpinAps) recently used the ALS to gain greater insight into vanadium dioxide’s unusual phase transition. ...
