Abstract
The energy released in a magnetic material by reversing spins as they relax toward equilibrium can lead to a dynamical instability that ignites self-sustained rapid relaxation along a deflagration front that propagates at a constant subsonic speed. Using a trigger heat pulse and transverse and longitudinal magnetic fields, we investigate and control the crossover between thermally driven magnetic relaxation and magnetic deflagration in single crystals of -acetate.

Fire in a Quantum Mechanical Forest
Published 13 May 2013
A new experimental scheme allows the controlled generation and observation of magnetic avalanches, a cascade of spin flips that propagates through a magnetic sample like a three-dimensional fire.
