Ferrofluids as thermal ratchets [PDF]

open access: yesPhysical Review Letters, 2003
Colloidal suspensions of ferromagnetic nano-particles, so-called ferrofluids, are shown to be suitable systems to demonstrate and investigate thermal ratchet behavior: By rectifying thermal fluctuations, angular momentum is transferred to a resting ...
