Abstract :
In this work we will show that the ultimate potential of the composite/exchange spring media is realized if the interfacial domain wall fits inside soft and hard layers. We will analyze the potential of the "domain wall assisted magnetic recording" (DWAMR) using numerical micromagnetics, as well as analytical formulas derived for exchange spring magnets.
