Magnetic Anisotropy at Nanoscale

الملخص EN

Nanoscale objects often behave differently than their “normal-sized” counterparts.

Sometimes it is enough to be small in just one direction to exhibit unusual features.

One example of such a phenomenon is a very specific in-plane magnetic anisotropy observed sometimes in very thin layers of various materials.

Here we recall a peculiar form of the free energy functional nicely describing the experimental findings but completely irrelevant and thus never observed in larger objects.
