dc.description | Given is the model for unusual magnetic anisotropy observed in thin magnetic layers. Assuming that the surface is rippled (what is often observed), we obtain new formula: the magnetic anisotropy energy is proportional to the absolute value of cos(x) rather than to the series of even powers of cos(x). Here "x" is the angle between easy in-plane axis and the direction of external field. This paper has been triggered by experimental observation of the effect predicted few years ago by the current author. | en |
dc.description.abstract | 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. | en |
