Grain structure dependence of coercivity in thin films

15 Dec 2016 Bachleitner-Hofmann Anton Bergmair Bernhard Schrefl Thomas Satz Armin Suess Dieter

We investigated coercive fields of 200nm x 1200nm x 5nm rectangular nanocrystalline thin films as a function of grain size D using finite elements simulations. To this end, we created granular finite element models with grain sizes ranging from 5nm to 60nm, and performed micromagnetic hysteresis calculations along the y-axis (easy direction) as well as along the x-axis (hard direction)...
