There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect.
Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist.
The logic and memory functions of future electronic devices could shrink dramatically â€“ to one or two nanometers (billionths of a meter) instead of the many tens of nanometers that characterize todayâ€™s most advanced elements - if a way can be found to control domain walls, the ultrathin transition zones that separate regions of a material having different magnetic, electric, or other properties.
