                Anisotropy in magnetic thin films
          from ab-initio calculation to model systems


Anisotropy plays and important role in determining the magnetic 
structure of thin films. By the Mermin-Wagner theorem, long range order 
is impossible in its absence in low-dimensional systems. The competition 
of the contributions of different types of anisotropy gives rise to a 
wealth of magnetic phases from ferromagnetism to skyrmions. In the talk 
I will discuss the temperature dependence of isosotropy in detail. I 
will demonstrate the use of metadynamics, a new simulation technique, to 
explore the free energy of simple magnetic systems.
