Title:
METHOD OF SPIN RECORDING AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2006/001332
Kind Code:
A1
Abstract:
A method of spin recording that forms atom/molecule scale stable bits to thereby attain a striking increase of recording density. Compound single crystals containing transition metal atoms (ions) interspaced with a satisfactory distance in each single crystal exhibit paramagnetism, and each of the transition metal atoms (ions) has its intrinsic magnetic moment attributed to electrons of its incomplete shell. Further, each of the transition metal atoms (ions) produces magnetic anisotropy under the influence of crystal field. That is, the transition metal atoms (ions) of paramagnetic compounds fundamentally possess individual independent magnetic moments and magnetic anisotropies. In the proposed method, information (signal) is recorded by the use of the atomic magnetic moment of magnetic atoms (ions) existing in the neighborhood of the surface of paramagnetic crystal containing the above transition metal atoms (ions).
