In order to improve the durability of metal-film magnetic tapes, novel lubricants, A20H, X-1P, and X, a modified phosphazene, were deposited on the tapes. The adhesion, friction, and wear of the unlubricated/lubricated tapes were investigated using a

The magnetization reversal in epitaxial iron 〈1 1 1〉 films has been studied using MFM with in situ magnetic fields and, in addition, correlated with macroscopic data obtained by conventional magnetometry. Due to the crystallographic orientation a

Localized magnetic reversal of a perpendicular anisotropy thin film has been performed using the magnetostrictive response of the film to a force applied by probe tips of scanning force microscope cantilevers. Non-magnetic and magnetic cantilever tip

We have carried out studies of the magnetic reversal process of a rare earth–transition metal thin film with perpendicular magnetic anisotropy using a magnetic force microscope (MFM) capable of applying in situ magnetic fields. The magnetization of

We have imaged mechanically polished and fractured (1 1 1) surfaces of Terfenol-D using magnetic force microscopy (MFM), and also the fracture surface during application of in situ applied stresses. The theory of James and Kinderlehrer (Phil. Magn. B

The magnetic reversal mechanism of tapered permalloy bars with holes in the center was studied using a Magnetic Force Microscope with in situ magnetic field capability. The samples studied were lithographically patterned from a 20-nm-thick NiFe film

A combination of a lubricant layer and carbon layer is generally used to provide wear and corrosion protection to the magnetic layer in a magnetic medium. Typically, the carbon layer has a diamond-like structure doped with hydrogen and/or nitrogen. A

We have developed a technique to quantitatively image the magnetic field above a magnetic specimen using a modified magnetic force microscope (MFM). The technique depends on the nonlinear response of a magnetically soft MFM tip to the sample field an
