    "abstract": "We discuss the effects caused by a resonant cavity around a sample of a\nmagnetic molecular crystal (such as Mn${}_{12}$-Ac), when a time dependent\nexternal magnetic field is applied parallel to the easy axis of the crystal. We\nshow that the back action of the cavity field on the sample significantly\nincreases the possibility of microwave emission. This radiation process can be\nsupperradiance or a maser-like effect, depending on the strength of the\ndephasing. Our model provides further insight to the theoretical understanding\nof the bursts of electromagnetic radiation observed in recent experiments\naccompanying the resonant quantum tunneling of magnetization. The experimental\nfindings up to now can all be explained as being a maser effect rather than\nsuperradiance. The results of our theory scale similarly to the experimental\nfindings, i.e., with increasing sweep rate of the external magnetic field, the\nemission peaks are shifted towards higher field values.",
