Dipole-exchange spin waves in magnetic thin films at zero and finite temperature: Theory and simulations

A spin wave theory of magnetic thin films in the HOLSTEIN—PRIMAKOFF approximation is presented which includes cases like SC (100), SC (101), FCC (111), BCC (100) and hexagonal (0001) for any spin S. In the center of interest are the wave functions of the spin waves. Furthermore, a comparison is given with the theories of ABBEL 1 and JELITTO 2, both elaborated for spin S=1/2 and based on another formalism.

Cr thin films are often used as underlayers for Co alloy magnetic thin films, such as Co1, CoNi2, and CoNiCr3, for high density longitudinal magnetic recording. It is belived that the role of the Cr underlayer is to control the growth and texture of the Co alloy magnetic thin films, and, then, to increase the in plane coercivity of the films. Although many epitaxial relationship between the Cr underlayer and the magnetic films, such as ﹛1010﹜Co/ {110﹜Cr4, ﹛2110﹜Co/ ﹛001﹜Cr5, ﹛0002﹜Co/﹛110﹜Cr6, have been suggested and appear to be related to the Cr thickness, the texture of the Cr underlayer itself is still not understood very well. In this study, the texture of a 2000 Å thick Cr underlayer on Nip/Al substrate for thin films of (Co75Ni25)1-xTix dc-sputtered with - 200 V substrate bias is investigated by electron microscopy.
