Saving energy: New method guides magnetism without magnets

In a leap toward greener tech, researchers at the Paul Scherrer Institute have discovered a way to control magnetic textures using electric fields no bulky magnets needed. Their star material? A strange crystal called copper oxyselenide, where magnetic patterns like helices and cones swirl at low temperatures. By zapping it with different electric fields, they could bend, twist, and even flip these patterns a first in the world of magnetoelectrics. This opens the door to ultra-efficient data storage, sensors, and computing, all while saving tons of energy.
