It’s amazing what a little spin pumping can do

In 2016 researchers at Spintec used spin pumping to study spin fluctuations in ultra-thin layers. More recently, they joined forces with other researchers* to show that the method is generic in nature. In other words, it is effective regardless of whether an electric or magnonic current is used to transport the spin and regardless of whether the phase transition is of the ferromagnetic to paramagnetic or antiferromagnetic to paramagnetic type.

The research investigated several combinations of spin injecting and absorbing materials (spin pumping occurs from one to the other). This advance will make it easier to characterize the order of materials in nanolayered materials. Until now, characterization required advanced lithography techniques.
