摘要： An antiferromagnetic nanostructure according to one embodiment includes an array of at least two antiferromagnetically coupled magnetic atoms having at least two magnetic states that are stable for at least one picosecond even in the absence of interaction with an external structure, the array having a net magnetic moment of zero or about zero, wherein the array has 100 atoms or less along a longest dimension thereof. An atomic-scale structure according to one embodiment has a net magnetic moment of zero or about zero; two or more stable magnetic states; and having an array of atoms that has magnetic moments that alternate between adjacent magnetic atoms along one or more directions. Such structures may be used to store data at ultra-high densities.
