13. MAGNETIC MEDIA, MAGNETIZATION REVERSAL.

Author

Ross, C. A., Schabes, M. E., Nolan, T., Tang, K., Ranjan, R., and Sinclair, R.

Subjects
MAGNETIC fields, MAGNETIZATION, FERROMAGNETISM, PARAMAGNETISM, PHYSICAL sciences, ELECTRICITY
Abstract

This article describes the magnetization reversal processes and the time-dependent reversal phenomena that occur when data are stored in magnetic recording media. These reversal processes determine the response of the medium to the applied magnetic field during the writing of data and the stability of written data patterns over the lifetime of the medium. Information is written onto hard-disk magnetic recording media when a magnetic write head passes near the surface of the recording medium. The head is magnetized by a varying current whose polarity changes according to a digitized stream of data.

14. MAGNETIC MEDIA, IMAGING.

Author

Abstract

This article reports that magnetic imaging is used to examine small-scale magnetic features within materials, often on the submicrometer scale. There are several techniques available that give complementary information about the magnetization within and at the surface of a material and the magnetic field outside the material. Lorentz transmission electron microscopy and electron holography are transmission electron microscope techniques sensitive to the magnetic field experienced by a beam of electrons passing through a sample. Scanning electron microscopy with polarization analysis and the magneto optical Kerr effect (MOKE) are sensitive to the magnetization state of the material near the surface of a sample. MOKE, is limited by the wavelength of light, but has been particularly useful for imaging domain patterns in samples such as permalloy pole pieces in recording heads.
