» Nebraska-MRSEC researchers in collaboration with researchers in Spain and at the University of Wisconsin have discovered a significantly more efficient method of data storage that offers great promise for the future of technology. To date, researchers have relied on the electrical voltage to store information. However, Gruverman's team found that the same bit could be written simply by pressing harder against the ferroelectric material's surface. In a sense and in this case, the probe's needle works much like a nanoscopic typewriter in its ability to write data in a very specific area on a ferroelectric film and leave data behind without damaging the surface. That finding makes the research team the first to demonstrate that mechanical force can be used to change an area’s polarization.

» Nebraska-MRSEC researchers have made a significant breakthrough in the field of spintronics. For the first time they changed the orientation of a very large number of electron spins collectively at room temperature by pure electrical means, a feature that could eventually make devices that use spintronics more readily available for everyday uses. Their method could revolutionize information technology by reducing power consumption, providing faster processing speeds and improving device function as compared to today's electronics.
