Electromagnetic radiation emanating from the molecular nanomagnet Fe8

Photons emitted by transition between the discrete levels of single molecular magnets might obay the elementary condition for Dicke's super-radiance. We investigate this possibility in the Fe8 molecule where magnetization jumps are known to occur at discreet magnetic field values. We found energy bursts each time the molecule undergoes a magnetization jump, confirming their quantum nature. A series of tests indicated that photons carry out the energy, and that indeed these photons obey the elementary conditions for super-radiance.
