In this project we will research disordered magnetic alloys from first principles. Researching magnetic properties of disordered alloys is essential for the knowledge of phase transformations in alloys and also from the viewpoint of fundamental concerns of magnetism in solids. Actually Disorder in a magnetic system can lead to unusual magnetic structures, as an example spin glass, which have somewhat unusual features.
The interaction between light and organometallic chromophores has been looked into theoretically in a strive for fast optical filters. The key focus is on two-photon absorption and excited state absorption as highlighted in the Jablonski diagram. We stress the need for relativistic
This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior.
Ti-Si-N and Ti-Al-Si-N thin solid films have been studied by analytical electron microscopy, X-ray diffraction, scanning tunneling microscopy, X-ray photoelectron spectroscopy, elastic recoil detection analysis, nanoindentation, and ab initio calculations. I find that arc evaporated (Ti1-xSix)Ny films can be grown as cubic
Diamond is an important material in many industrial applications (e.g., machining of hard materials, bio-electronics, optics, electronics, etc.) because of its exceptional properties such as hardness, tolerance to aggressive environments, compatibility with human tissues, and high carrier mobility. However, a highly controlled
