The spin is the intrinsic angular momentum of electrons that produces a magnetic moment. Coupling these magnetic moments creates the magnetism that could ultimately be used in <a href=\"https:\/\/phys.org\/tags\/information+processing\/\" rel=\"tag\" class=\"\">information processing<\/a>. When these coupled <a href=\"https:\/\/phys.org\/tags\/magnetic+moments\/\" rel=\"tag\" class=\"\">magnetic moments<\/a> are locally excited by a <a href=\"https:\/\/phys.org\/tags\/magnetic+field\/\" rel=\"tag\" class=\"\">magnetic field<\/a> pulse, this dynamic can spread like waves throughout the material. These are referred to as spin waves or magnons.<\/p>\n<p>A special type of those waves is at the heart of the work of the physicists from Halle. Normally, the non-linear excitation of magnons produces integers of the output frequency\u20141,000 megahertz becomes 2,000 or 3,000, for example.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Strong alternating magnetic fields can be used to generate a new type of spin wave that was previously just theoretically predicted.
