Abstract :
Behavior of perpendicular orientation of the acicular ( ratio 7/1 ) and ultra fine ( 
m) particles in the thin coating type media was investigated by magnetic measurements. The perpendicular anisotropy coatings which contain the acicular γ-Fe2 O3 particles or Co-γ-Fe2 O3 particles can be obtained by a continuous process line. The degree of perpendicular orientation of the moments or the particles in the tapes are discussed by the measurements of Mössbauer spectra.
