Engineering researchers develop a process that could make big data and cloud storage more energy efficient

As big data and cloud applications flourish, one of the grand challenges for future computing is finding energy-efficient methods for data storage. Magnetic material is commonly used for data storage — think of magnetic strips on the back of a credit card — and the ability to flip the “polarity” (magnetization direction) of magnetic particles that are retained for long periods of time without needing power is essential to nonvolatile magnetic memory. A group of researchers at the Virginia Commonwealth University School of Engineering has developed a process to bring about this flipping of magnetic “polarity.” The group’s method offers a significant reduction in energy required for big data and cloud memory storage.”
