Researchers have discovered proof that acoustic phonons, the elemental particles that transmit both heat and sound, have magnetic properties. In a new paper, the authors describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by 12 percent. But because the phonons reacted to the magnetic field, the particles must be sensitive to magnetism. read more
