Surprising quantum effect in hard disk drive material (https://www.sciencedaily.com/releases/2019/04/190426075432.htm)
As reported in a recent issue of Physical Review Letters, researchers from the U.S. Department of Energy's (DOE) Argonne National Laboratory, along with Oakland University in Michigan and Fudan University in China, have found a surprising quantum effect in this alloy.
The effect involves the ability to control the direction of electron spin, and it could allow scientists to develop more powerful and energy-efficient materials for information storage. By changing the electron spin direction in a material, the researchers were able to alter its magnetic state. This greater control of magnetization allows more information to be stored and retrieved in a smaller space. Greater control could also yield additional applications, such as more energy-efficient electric motors, generators and magnetic bearings.

Cool! I'm running out of space for my child-por- I mean landscape images so this can't happen soon enough.
