Ultrathin metal layer boosts spin-related signals, opening a door to ultralow-power electronics

Researchers at Kyushu University have found that an ultrathin layer of iridium manganese (IrMn) can improve two spin-related signals in a structure made of a magnetic insulator and a platinum film. By examining how spin currents are generated and absorbed, the team gained insights into how the intermediate layer improves spin transfer. The findings could inform the development of ultralow-power devices for computing and energy harvesting.
