Autor: M Zwiebler, J E Hamann-Borrero, M Vafaee, P Komissinskiy, S Macke, R Sutarto, F He, B Büchner, G A Sawatzky, L Alff, J Geck

Publikováno v: New Journal of Physics, Vol 17, Iss 8, p 083046 (2015)

The analysis of x-ray reflectivity data from artificial heterostructures usually relies on the homogeneity of optical properties of the constituent materials. However, when the x-ray energy is tuned to the absorption edge of a particular resonant sit

Publikováno v: Scientific reports

Interface engineering in complex oxide superlattices is a growing field, enabling manipulation of the exceptional properties of these materials, and also providing access to new phases and emergent physical phenomena. Here we demonstrate how interfac

The interface between the insulators LaAlO$_3$ and SrTiO$_3$ accommodates a two-dimensional electron liquid (2DEL) -- a high mobility electron system exhibiting superconductivity as well as indications of magnetism and correlations. While this flagsh

Comparative fecundity of the imperiled crayfishFaxonius quadruncusCreaser and invasive crayfishFaxonius hylas(Faxon) in the St. Francis River drainage of Missouri, USA

Autor: Mary R. Mabery, Robert J. DiStefano, Catlin W. Ames, Jordan S. Macke, Dusty A. Swedberg

Publikováno v: Freshwater Crayfish. 23:13-21

Knowledge of crayfish species’ life history traits is vital to their conservation and management. Fecundity is one trait that is a likely indicator of extinction risk and potential invasiveness. Fecundity-related data are lacking for the imperiled

Complex magnetic order in nickelate slabs

Magnetic ordering phenomena have a profound influence on the macroscopic properties of correlated-electron materials, but their realistic prediction remains a formidable challenge. An archetypical example is the ternary nickel oxide system RNiO3 (R =

Advanced functional materials

Thickness driven electronic phase transitions are broadly observed in different types of functional perovskite heterostructures. However, uncertainty remains whether these effects are solely due to spatial confinement, broken symmetry or rather to a

Combining dissimilar transition metal oxides (TMOs) into artificial heterostructures enables to create electronic interface systems with new electronic properties that do not exist in bulk. A detailed understanding of how such interfaces can be used
