Charge delocalization and hyperpolarizability in ionic liquids
C. D. Rodriguez-Fernandez L. M. Varela, C. Schroder, E. Lopez Lago
In this work the role that charge delocalization plays in the non-linear optical response of ionic liquids is evaluated. The first hyperpolarizability for the non-linear process of…
Metamagnetic phase transition of the antiferromagnetic Heisenberg icosahedron
Christian Schröder, Heinz-Jürgen Schmidt, Jürgen Schnack +1
The observation of hysteresis effects in single molecule magnets like Mn-acetate has initiated ideas of future applications in storage technology. The appearance of a hyster…
Competing Spin Phases in Geometrically Frustrated Magnetic Molecules
C. Schroeder, H. Nojiri, J. Schnack +3
We have found a class of zero-dimensional geometrically frustrated Heisenberg spin systems exhibiting anomalous behavior in an external magnetic field B similar to that occuring in…
