| 主权项 | 1. A system, comprising: at least one magnetic nanoparticle; a heating device for heating the at least one magnetic nanoparticle to induce a paramagnetic thermal instability in the at least one magnetic nanoparticle whereby a magnetization of the magnetic nanoparticle randomly switches between different detectable magnetic states upon heating thereof; and a magnetoresistance reading device for detecting an instantaneous magnetic state of the magnetic nanoparticle, wherein the at least one magnetic nanoparticle has binary anisotropy, wherein a length of the at least one magnetic nanoparticle is greater than a width of the at least one magnetic nanoparticle, wherein a deposition plane of the magnetoresistance reading device is about parallel to a surface of a substrate upon which the at least one magnetic nanoparticle resides. | ||
