Nanoscale multiferroic materials open the path to efficient magnetic memory technology
Researchers have demonstrated that nanoscale multiferroic materials can be used to create energy-efficient magnetic memory devices. By using electric fields rather than magnetic fields to switch magnetic states, these materials could significantly reduce the energy consumption of data centers and AI hardware.
Why it matters
As global energy demand for AI and cloud computing surges, developing nonvolatile, low-power memory technologies is critical for sustainable technological growth.

DOI: 10.1126/sciadv.aec2861 With the rapid spread of cloud computing, artificial intelligence and data centers, global energy consumption is rising to new heights. A promising way to reduce this burden is to develop memory devices that store information magnetically yet are written using electric fields. Magnetic memories are nonvolatile, meaning stored information is retained without a power supply.
