In this Letter, the authors report an AC conductivity analysis on the [Fe(Htrz)2(trz)](BF4) spin crossover complex and reveal the spin-state dependence of the electrical conductivity, permittivity and modulus in a broad frequency range. This study confirms recent findings in spin-state dependent conductivity measurements and highlights a unique behavior of the relaxation frequencies of charge carriers.

A substantial aspect of semiconductor spintronics is the generation of spin currents. This goal may be achieved by schemes that rely on pumping of electrons through interacting quantum dots. Their appeal lies in the tunability of the pumping characteristics via gate voltages. We put special focus on the possibility of pure spin pumping in the absence of charge pumping.

Chalcogenide glasses and phase-change alloys are characterised by pronounced bonding energy hierarchy between co-aligned shorter and longer (resonant) bonds. The existing experimental and simulational evidence suggests that it is this hierarchy that makes athermal amorphisation of these materials possible.

Atomistic simulations at two levels, classical and quantum-mechanical, are performed to probe the binding possibilities of the smallest multi-shelled concentric fullerenes, known as ‘carbon onions’. Their binding is promoted through the addition of vacancies and doping. Optimizing the conditions for assembling these nanoscale building blocks will be important for creating novel functional nanomaterials.
