Figure 1: (a) Schematic of the setup developed by Subedi et al. [1]: A heater triggers a magnetic avalanche in a single Mn12-acetate crystal, and magnetic sensors monitor the propagation of the spin reversal front across the sample. (b)-(d) Schematic of an avalanche in Mn12-acetate: (b) impulsive heating causes one spin to flip, releasing its Zeeman energy to a few neighboring spins; (c) these spins flip, heating their neighbors; (d) the process repeats itself in cascade and a magnetic “deflagration” results.
