University of California developed magnetic calculation switch

Currently, microprocessors have a current flowing in the transistor, and the device generates heat and leaks a small amount of current at the same time, resulting in a decrease in chip efficiency. To this end, researchers at the University of California, Los Angeles use multiferromagnetic materials to reduce the power consumption of logic circuits.

Multiferroic materials can be turned on or off by changing the voltage, which enables it to transmit energy in the form of cascaded waves through electron spins. This magnetic effect is called the spin wave bus. It can also be thought of as waves, waves can transmit energy, but individual water molecules do not move.

The researchers said that the use of spin waves can help people achieve a new way of computing, which will help solve the traditional semiconductor technology is facing the proportion of reduced challenges. And, the spin waves generated by this multiferroic material can also reduce the heat loss in the calculation process, thereby increasing the energy efficiency by 1000 times.
