Critical fields in ferromagnetic thin films: identification of four regimes (Q851206)

This paper is basically a supplement to the paper \textit{R. Cantero-Alvariez} and \textit{F. Otto} [J. Nonlinear Sci. 16, No. 4, 385--413 (2006; Zbl 1129.78017)], reviewed previously. It deals with the ``concertina pattern'' in low-crystalline anisotropic ferromagnetic thin film elements. The authors calculate conditions for the phenomena to become apparent and compare the results of the analysis with some experimental results. The agreement is only of the same order of magnitude and not of reasonable closeness. They discuss the phenomenon of magnetization ripple, involving several lemmas and corollaries. Following a long analysis, it is shown how to resolve the discrepancy.
