Abstract: 
The magnetization reversal process in specially prepared uniaxial thin films of nickel—iron alloy is studied by measurements of the 400 c.p.s. hysteresis loops. The results indicate that both coherent rotation and domain wall motion can occur in the same film, but in different proportions according to the orientation of the anisotropy axis with respect to the applied field and the thickness of the film. Special properties of these films are discussed for fields applied normal to the anisotropy axis.

Partial Rotation in Permalloy Films

S. Methfessel, +2 more
- 01 Oct 1961 - 
TL;DR: In this paper, the inversion of Permalloy films with different values of coercive force was studied and the hysteresis properties showed that ''inverted'' films do not represent a special case, but that every film exhibits inversion in a certain sector of field direction.

Magnetization Hysteresis Loop Tracer for Long Specimens of Extremely Small Cross Section

E. C. Crittenden, +2 more
- 01 Dec 1951 - 
TL;DR: In this paper, an instrument for measurement of the low frequency magnetic properties of thin layers is described, where the difference signal from two opposed pick-up coils is amplified, integrated, and amplified again to cause the vertical deflection of a cathode-ray oscillograph to be proportional to the intensity of magnetization of the specimen.
