Title

Magnetic deflagration in Gd5Ge4

AbstractWe report experiments on magnetic avalanches in the intermetallic compound Gd5Ge4. Kinetics of the avalanches have been studied and compared with the theory of magnetic deflagration. We show that the data fit well into the theoretical framework of deflagration. This adds Gd5Ge4 to the growing family of materials (that now includes molecular magnets and manganites) which exhibit this phenomenon. The “burning” of the metastable magnetic phase involves a magnetostructural transition alongside the reordering of spins.
