Berkeley Lab Researchers Unlock Ferromagnetic Secrets of Promising Materials

Spintronic technology, in which data is processed on the basis of electron “spin” rather than charge, promises to revolutionize the computing industry with smaller, faster and more energy efficient data storage and processing. Materials drawing a lot of attention for spintronic applications are dilute magnetic semiconductors – normal semiconductors to which a small amount of magnetic atoms is added to make them ferromagnetic. Understanding the source of ferromagnetism in dilute magnetic semiconductors has been a major road-block impeding their further development and use in spintronics. Now a significant step to removing this road-block has been taken.

A multi-institutional collaboration of researchers led by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), using a new technique called HARPES, for Hard x-ray Angle-Resolved PhotoEmission Spectroscopy, has investigated the bulk electronic structure of the prototypical dilute magnetic semiconductor gallium manganese arsenide. Their findings show that the material’s ferromagnetism arises from both of the two different mechanisms that have been proposed to explain it. (more…)

New IBM Software Helps Strengthen Security of Mobile Devices in the Workplace

Increases in mobile exploits and concerns from security executives around BYOD adoption leads to enhanced security intelligence capabilities

ORLANDO – 05 Jun 2012: IBM today announced new software to help organizations develop mobile applications that are more secure by design. Now,

clients can build security into the initial design of their mobile applications so that vulnerabilities will be detected early in the development process. Today’s announcement further expands IBM’s strategy to provide clients with a mobile platform that spans application development, integration, security and management.

With more than five billion mobile devices in the world – and only 2 billion computers – the shift to mobile devices as the primary form of connecting to corporate networks is increasing rapidly. Securing those devices is becoming a top priority for security executives and CIOs. As companies embrace the growing “Bring Your Own Device” (BYOD) trend, the need to secure the applications that run on these devices is becoming more critical. According to the 2011 IBM X-Force Trend and Risk Report, mobile exploits increased by 19 percent in 2011. In addition, according to the recently released data from the IBM Center for Applied Insights study, 55 percent of respondents cited mobile security as a primary technology concern over the next two years.
