6.3. The effects of thin-film epitaxy on magnetism
The greater field of magnetism is rich with thin-film phenomena (Bader, 1990). From magnetic size effects including diminished magnetization in ultrathin films, decreased magnetocrystalline anisotropy, and epitaxial strain-induced changes in properties, one must consider the effects of changing material geometry and the elastic boundary conditions on the evolution of magnetic properties.

6.3.1.1. Magnetic dead layers in La0.7Sr0.3MnO3
Dimensionally confining the thickness of a thin film is a common approach to tune its properties, but in some magnetic oxides one must be aware of so-called magnetic dead layers. Combined spin-resolved photoemission spectroscopy, SQUID magnetometry, ...
