For about ten years now, tiny magnetic structures measuring a few millionths of a millimetre have met with growing interest from the worlds of science and technology, particularly on account of their ...

(PhysOrg.com) -- Magnetic vortex cores, which can be used as particularly stable storage points for data bits, can now be switched much faster. An edge length of a mere thousandth of a millimetre and ...

A data point changes the polarisation: The detail of the sample shows how the magnetization is switched from upwards to downwards. © M. Kammerer / MPI for ...

Untethered magnetic needles can perform less invasive, more precise surgery, researchers report. Imagine a tiny, untethered needle that can enter the body through an incision no larger than a pin ...

Imagine a tiny, untethered needle that can enter the body through an incision no larger than a pin prick to perform biopsies, suture wounds, and even deliver cancer-fighting chemotherapy directly to ...

If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...

Scientists at the Max Planck Institute of Metals Research in Stuttgart have discovered a new mechanism with which it is possible to use weak magnetic fields to reverse tiny magnetic structures, called ...

(Nanowerk News) Microscopically tiny ferromagnetic platelets exhibit a phenomenon which could be exploited in the future for particularly stable magnetic data storage: so-called magnetic vortex cores.
