Flux through a hole from a shaken granular medium
K. Chen, M. B. Stone, R. Barry +7
We have measured the flux of grains from a hole in the bottom of a shaken container of grains. We find that the peak velocity of the vibration, vmax, controls the flux, i.e., the f…
Studies of local jamming via penetration of a granular medium
M. B. Stone, R. Barry, D. P. Bernstein +3
We present a series of measurements examining the penetration force required to push a flat plate vertically through a dense granular medium, focusing in particular on the effects…
Field-induced avalanche to the ferromagnetic state in the phase-separated ground state of manganites
F. M. Woodward, J. W. Lynn, M. B. Stone +5
Perovskite manganite compounds such as Pr_(1-x)(Ca_(1-y)Sr_y)_xMn3 can be tuned to exhibit a metastable ground state where two magnetic/crystallographic phases coexist in zero magn…
Capping-induced suppression of annealing in Ga(1-x)Mn(x)As epilayers
M. B. Stone, K. C. Ku, S. J. Potashnik +3
We have studied the effects of capping ferromagnetic Ga(1-x)Mn(x)As epilayers with a thin layer of undoped GaAs, and we find that even a few monolayers of GaAs have a significant e…
