Researchers at the Spintec lab recently demonstrated that the spin current that propagates from one ferromagnetic layer to another can be doubled if the second layer has a fluctuating magnetic order. When the researchers heated the second layer to its magnetic phase-change temperature, the spin current was much greater.
And there are more ideas where that one came from! The researchers now plan to improve system efficiency and enhance the properties of the materials used. They are using the method to probe antiferromagnetic phase transitions, which are not magnetic.
The research could drive advances in future generations of devices without ferromagnetic materials.
