Magnetic imaging of spin waves and magnetic phase transitions with nitrogen-vacancy centers in diamond
The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.
