High pressure science is a rapidly growing diverse fi. e1d. The high pressure technique has become a powerful tool for both the study and preparation of materials. In spi. te of the many high pressure conferences held in recent years, I felt that the

Several series of sputtered Co(0.2 nm)/Ni (0.8 nm) multilayered films have been annealed up to 425/spl deg/C in air. The annealed samples maintain a perpendicular easy direction and have large magnetic coercivity values. For one annealing condition,

Spectroscopic (300-800 nm) magneto-optic measurements (polar Kerr rotation and ellipticity), as well as spectroscopic (250-1000 nm) ellipsometric measurements have been taken on a series of CoNi and TbCo multilayer nanostructures. The magnetic layers

Optical constants appropriate for ellipsometric thickness measurements have been determined for strained AlAs and InAs layers on an InP substrate with lattice matched InGaAs buffer layers. A procedure involving the simultaneous analysis of data from

A procedure involving normal-angle-of-incidence Kerr spectroscopy, variable-angle-of-incidence spectroscopic ellipsometry, and variable-angle-of-incidence spectroscopic magnetooptic ellipsometry has been developed. It makes it possible to extract lay

Spectroscopie ellipsometry is a well developed technique for studying the semiconductor materials and heterostructures. Here, we have applied this technique to in-situ studies of ZnSe and ZnCdSe growth in a low pressure organometallic vapor phase epi
