Induced Anisotropies in NiCo Obliquely Deposited Films and Their effect on Magnetic Domains

English Article: Oblique and in-plane anisotropies in obliquely evaporated NiCo thin films were investigated in order to understand their origin. All the compositions studied clearly show the effect of columnar grain morphology coupled with some intrinsic factors such as magnetostriction and crystallinity. Energy calculations are undertaken to explain the effect of

MAGNETIC STRUCTURE IN OBLIQUELY DEPOSITED Co-Au FILMS

Les couches minces de Co-Au de différentes compositions, déposées obliquement sous incidence de 40° et 60°, ont été étudiées. Les couches se caractérisent par un facteur de qualité Q > 1 ; les domaines en rubans "forts" se manifestent dans tous les échantillons ; les rubans faibles ont aussi pu être observés dans quelques couches déposées sous l'angle 40°.The magnetic properties and domain structure of Co-Au films of various compositions, deposeted at angles of incidence of 40° and 60° have been studied. Values of Q ranged from just under to well over 1. Strong stripe domains were obdserved in all specimens. Some specimens contained weak stripe domains as well

DOMAIN TIPS : STRUCTURE AND MOBILITY IN UNIAXIAL AMORPHOUS THIN FILMS

Statics and dynamics of domain tips have been investigated by high resolution Kerr effect using digital contrast enhancement. The magnetic structure is affected by demagnetizing effect. The internal wall structure is visible and a transition between asymmetric Bloch wall to Néel one is shown. Tip propagation along the easy axis is measured
