The new design takes advantage of magnetic vortices&#8217; ability to store binary information as positive or negative core polarities, which can be controlled by simply changing the frequency of the rotating vortex cores of the nanodots.<\/p>\n<p>The new technique, called frequency-controlled magnetic vortex memory, was developed by a team of researchers, B. Pigeau, et al., from France, Germany, and the US. Their study is published in a recent issue of<em> <a rel=\"tag\" href=\"http:\/\/www.physorg.com\/tags\/applied+physics+letters\/\">Applied Physics Letters<\/a><\/em>.<\/p>\n<p>As the researchers explain, the concept of using magnetic nano-objects to store binary information for magnetic RAM has previously been investigated, but it\u2019s been difficult to find a mechanism to reverse the magnetization inside individual nano-objects. Here, the researchers achieve this reversal by using microwave pulses in combination with a static magnetic field. In this scheme, large and small rotating core frequencies are associated with positive and negative core polarities, respectively. In a positive core polarity, the core is parallel to the applied magnetic field, while in a negative core polarity, the core is antiparallel to the applied magnetic field. An extremely sensitive magnetic resonance force microscope (MRFM) is used to address the\u00a0<a rel=\"tag\" href=\"http:\/\/www.physorg.com\/tags\/resonant+frequency\/\">resonant frequency<\/a> of magnetic nanodots\u2019 vortex core rotations, allowing the researchers to control the polarity states of individual nanodots.<\/p>\n<\/blockquote>\n<p>  <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/gocomments\/davidkirkpatrick.wordpress.com\/7314\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/comments\/davidkirkpatrick.wordpress.com\/7314\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/godelicious\/davidkirkpatrick.wordpress.com\/7314\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/delicious\/davidkirkpatrick.wordpress.com\/7314\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/gostumble\/davidkirkpatrick.wordpress.com\/7314\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/stumble\/davidkirkpatrick.wordpress.com\/7314\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/godigg\/davidkirkpatrick.wordpress.com\/7314\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/digg\/davidkirkpatrick.wordpress.com\/7314\/\" \/><\/a> <a rel=\"nofollow\" href=\"http:\/\/feeds.wordpress.com\/1.0\/goreddit\/davidkirkpatrick.wordpress.com\/7314\/\"><img decoding=\"async\" alt=\"\" border=\"0\" src=\"http:\/\/feeds.wordpress.com\/1.0\/reddit\/davidkirkpatrick.wordpress.com\/7314\/\" \/><\/a> <img data-recalc-dims=\"1\" decoding=\"async\" alt=\"\" border=\"0\" src=\"https:\/\/i0.wp.com\/stats.wordpress.com\/b.gif?w=780\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Through magnetic nanodots.
