Switching a nanomagnet is all in the timing

Image Thumbnail
Jonathan Sun, Physics 1, 33 (2008) – Published November 3, 2008
If a magnet is small enough, an electric current carrying polarized spins can flip it around. Scientists are finding clever ways to control this spin-torque effect precisely, both for when it is wanted and when it is not.
