Physical Review Letters – 8 August 2003
Volume 91, Issue 6

Angle-time plot of a model potential for the direction of a magnetic dipole (a nanoparticle in a ferrofluid) placed in an oscillating magnetic field. Full lines are long-time, deterministic solutions; dashed lines show noise-induced transitions between these. An average rotation of the particle results from different probabilities for forward- and backward-slip transitions. [Andreas Engel, Hanns Walter Müller, Peter Reimann, and Achim Jung, Phys. Rev. Lett. 91, 060602 (2003)]
