Charge and Magnetization Inhomogeneities in Diluted Magnetic Semiconductors
Carsten Timm
It is predicted that III-V diluted magnetic semiconductors can exhibit stripe-like modulations of magnetization and carrier concentration. This inhomogeneity results from the stron…
Collective effects in spin-crossover chains with exchange interaction
Carsten Timm
The collective properties of spin-crossover chains are studied. Spin-crossover compounds contain ions with a low-spin ground state and low lying high-spin excited states and are of…
Theory for transport through a single magnetic molecule: Endohedral N@C60
Florian Elste, Carsten Timm
We consider transport through a single N@C60 molecule, weakly coupled to metallic leads. Employing a density-matrix formalism we derive rate equations for the occupation probabilit…
Ground-state phases in antiferromagnetic spin-crossover chains
Carsten Timm, Ulrich Schollwöck
Spin-crossover molecules having a low-spin ground state and a low-lying excited high-spin state are promising components for molecular electronics. We theoretically examine one-dim…
Defect correlations, metal-insulator transition, and magnetic order in ferromagnetic semiconductors
Carsten Timm, Felix von Oppen
Diluted ferromagnetic III-V semiconductors typically show a high degree of compensation. Compensation is connected to the presence of comparable densities of charged defects of eit…
