Ve. Zubov et al., ANOMALOUS INFLUENCE OF PHYSICAL ADSORPTION ON THE MAGNETIC-PROPERTIESOF IRON SINGLE-CRYSTALS, Journal of magnetism and magnetic materials, 160, 1996, pp. 19-20
An essential distinction between the surface and volume dynamic proper
ties of 180 degrees domain walls in iron whiskers that is not explaine
d by the existent theory is determined. With the help of magneto-optic
al investigations in a vacuum cell, it is established that the reason
for the abnormal behaviour of domain walls is the physical adsorption
of molecules contained in the air on the whisker surface.
