A method of measuring surface curvature comprises forming an intensity distribution defined by Fresnel diffraction, wherein said intensity distribution is formed by electromagnetic radiation reflected from a surface, obtaining data for the intensity distribution and determining information relating to the curvature of the surface using the obtained data.

Apparatus and method for measuring the deformation of a tethered or untethered cantilever by projecting a radiation beam onto the cantilever, detecting an interference pattern reflected from or transmitted through the cantilever, and calculating the deformation of the cantilever by measuring the intensity variation within at least a portion of the interference pattern.

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