Lorentz TEM imaging of stripe structures embedded in a soft magnetic matrix
N\'eel walls in soft magnetic NiFe/NiFeGa hybrid stripe structures surrounded
by a NiFe film are investigated by high resolution Lorentz transmission
electron microscopic imaging. An anti-parallel orientation of magnetization in
1000 nm wide neighboring unirradiated-irradiated stripes is observed by forming
high angle domain walls during magnetization reversal. Upon downscaling the
stripe structure size from 1000 nm to 200 nm a transition from a discrete
domain pattern to an effective magnetic medium is observed for external
magnetic field reversal. This transition is associated with vanishing ability
of hosting high angle domain walls between adjacent stripes. The investigation
also demonstrated the potentiality of Lorentz microscopy to image periodic
stripe structures well under micron length-scale.Comment: 7 pages, 6 figure
