In a recent issue of the journal Nature Materials, the researchers describe how a magnetic field, roughly the size of a medical MRI, reduced the amount of heat flowing through a semiconductor by 12 percent. Simulations performed at OSC then identified the reason for it the magnetic field induces a diamagnetic response in vibrating atoms known as phonons, which changes how they transport heat. “We’ve shown that we can steer heat magnetically.
