Abstract : The study describes the fundamental behavior of a single magnetic domain under the influence of magnetic fields at small angles to the film normal. The longitudinal and transverse data are compared, and it is found, for the cases considered, that the single domain theory is valid, with the reservation that at low fields, domain formation produces an apparent attenuation of the transverse data. The apparent success of this study is compared to those by Jurretschke, and Ke and Juritsyna, is possibly due to the investigation of the governing equilibrium conditions. For each distinct field position, the solutions obtaining from these conditions are not necessarily continuous or minimum energy solutions, and care must be taken to assure that the minimum energy condition is satisfied.
