Each of the magnetic properties can hold information in multiple states. For example, if researchers can reliably distinguish between 8 different magnetization strengths by precisely controlling voltage application time, then a single nanodot could effectively store 8 different values (instead of just 0 or 1).
“The voltage actuation procedure, instead of using electric current, prevents heating in devices such as laptops, servers, and data centers. It drastically reduces energy loss,” noted Dr. Irena Spasojević, first author of the study, in a press release.
