摘要: A method for manipulating domain pinning and reversal in a ferromagnetic material comprises applying an external magnetic field to uniaxial comprising plurality of domains, where each has easy axis oriented along predetermined direction. The is applied transverse the direction at temperature. strength varied temperature, thereby isothermally regulating domains. storage device controlling dynamics includes hard disk material, recording head including first magnet, second magnet. domains having magnet positioned adjacent configured apply
