Magnetically Actuated Colloidal Microswimmers
The Journal of Physical Chemistry B, 2008 To achieve permanent propulsion of micro-objects in confined fluids is an elusive but challenging goal that will foster future development of microfluidics and biotechnology. Recent attempts based on a wide variety of strategies are still far from being able to design simple, versatile, and fully controllable swimming engines on the microscale. Here we

Light- and magnetically actuated FePt microswimmers [PDF]
The European Physical Journal E, 2021 AbstractExternally controlled microswimmers offer prospects for transport in biological research and medical applications. This requires biocompatibility of the swimmers and the possibility to tailor their propulsion mechanisms to the respective low Reynolds number environment.

Magnetically Actuated Liquid Crystals
Nano Letters, 2014 Ferrimagnetic inorganic nanorods have been used as building blocks to construct liquid crystals with optical properties that can be instantly and reversibly controlled by manipulating the nanorod orientation using considerably weak external magnetic fields (1 mT).

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Clearance change between a magnetic head with a thermal flying-height control (TFC) function and a magnetic disk at high altitude was investigated. To clarify the change of head-disk clearance in the case of TFC actuation at high altitude, head-disk ...
