Angle-resolved Photoemission Spectroscopy At Ultra-low Temperatures [PDF]

Journal of Visualized Experiments, 2012
The physical properties of a material are defined by its electronic structure. Electrons in solids are characterized by energy (ω) and momentum (k) and the probability to find them in a particular state with given ω and k is described by the spectral function A(k, ω).

High Temperature Oxidation of Ultra-Low-Carbon Steel [PDF]

Defect and Diffusion Forum, 2006
An oxide scale layer always forms at the strip surface during the hot rolling process. Its properties have a large impact on surface quality. The most important features of the oxide layer are its thickness, composition, structure, adherence and coherence. Temperature, time and gas atmosphere determine the growth of oxide layers.

Nuclear demagnetization for ultra-low temperatures

Cryogenics, 2014
Nuclear demagnetization is one of the most successful methods of cooling an appreciable amount of matter to the lowest temperatures. The principle of nuclear demagnetization is the same as that of the adiabatic demagnetization of a paramagnetic salt; however, there is a significant difference in practice. This article focuses on nuclear demagnetization
