Yellen and Lawrence N. Virgin<br/>The nonlinear dynamic behavior of superparamagnetic beads exposed to a periodic array of micromagnets and an external rotating field is simulated as a function of the relative size of the bead with respect to the micromagnet size and the strength of the external field relative to the pole density of...<br/>[Phys.

Lacoste, C. Brangbour, J. Bibette, and J. Baudry<br/>We study the thermal expansion of chains formed by self-assembly of magnetic colloidal particles in a magnetic field. Using video microscopy, complete positional data of all the particles of the chains is obtained. By changing the ionic strength of the solution and the applied magnetic field, the in...<br/>[Phys.

Guery, J. Baudry, D. A. Weitz, P. M. Chaikin, and J.

Tensile stress can affect the activation energy but definitive experiments of the diffusion rate of species through a stressed solid are lacking.
