Spintronics is not an excercise regime...

What is the future of magnetic memory and logic devices?

Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and Cornell University successfully used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature.

SO WHAT you say...

This runs counter to conventional scientific wisdom, points a new way towards spintronics and smaller, faster and cheaper ways of storing and processing data.

the best thing is its massively more energy-efficient so battery life will be better.

The senior author of a paper describing this research in Nature. The paper is titled "Deterministic switching of ferromagnetism at room temperature using an electric field." John Heron, now with Cornell University, is the lead and corresponding author.

Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist. They are viewed as potential cornerstones in future data storage and processing devices because their magnetism can be controlled by an electric field rather than an electric current, a distinct advantage on current devices...
