Propagation of avalanches in Mn12-acetate: magnetic deflagration.

Local time-resolved measurements of fast reversal of the magnetization of single crystals of Mn12-acetate indicate that the magnetization avalanche spreads as a narrow interface that propagates through the crystal at a constant velocity that is roughly 2 orders of magnitude smaller than the speed of sound. We argue that this phenomenon is closely analogous to the propagation of a flame front (d...

Quantitative Scaling of Magnetic Avalanches.

We provide the first quantitative comparison between Barkhausen noise experiments and recent predictions from the theory of avalanches for pinned interfaces, both in and beyond mean field. We study different classes of soft magnetic materials, including polycrystals and amorphous samples-which are characterized by long-range and short-range elasticity, respectively-both for thick and thin sampl...

Validation of the Propagation Saw Test near Whumpfs and Avalanches

The Propagation Saw Test (PST) is a recently developed field test method for evaluating the fracture propagation propensity of slab and weak layer combinations. The PST is intended to replicate the fracture propagation behaviour found on nearby slopes. By following a simple interpretation guideline, PST results can indicate the propensity of a given snowpack to propagate weak layer fractures to...

Thermal and Magnetic Characteristics of Cellulose Acetate- Fe3O4

Fe3O4 nanoparticles were synthesizedviaa simple chemical reaction between FeCl2.4H2O and Fe(NO3)3.9H2O under nitrogen atmosphere at room temperature, and then nanoparticles were added to cellulose acetate (CA) polymer. The influence of nanoparticles on the thermal properties of CA polymeric matrix was studied using the...
