Abstract

We report our study on magnetic structural evolution of artificially patterned micron and submicron magnetic arrays as a function of applied field using in situ electron microscopy. To understand magnetic dynamics and switching behavior we employ our newly developed phase retrieval method, based on Lorentz phase microscopy, to map local induction distribution at nanometric scale. We outline the principle of the new method and discuss its advantages and drawbacks in comparison with off-axis electron holography.
