Large-Amplitude Spin Dynamics Driven by a THz Pulse in Resonance with an Electromagnon

Christoph Peter Hauri

Multiferroics have attracted strong interest for potential applications where electric fields control magnetic order. The ultimate speed of control via magnetoelectric coupling, however, remains largely unexplored. Here, we report an experiment in which we ...

Engineering quantum spin Hall effect in graphene nanoribbons via edge functionalization

Oleg Yazyev, Gabriel Albert Autes

Kane and Mele predicted that in the presence of spin-orbit interaction graphene realizes the quantum spin Hall state [Phys. Rev. Lett. 95, 226801 (2005)]. However, exceptionally weak intrinsic spin-orbit splitting in graphene (approximate to 10(-5) eV) inh ...

Composite pulses for efficient excitation of half-integer quadrupolar nuclei in NMR of static and spinning solid samples

Geoffrey Bodenhausen, Diego Carnevale

Composite pulses of the type (tau(p))(x)(2 tau(p))(-x)(3 tau(p))(x) allow one to excite the central transition of nuclei with half-integer spin with enhanced efficiency compared to a simple (tau(sp)(p))(x) pulse. The method has been tested on solid samples ...

The Quantum Magnetism of Individual Manganese-12-Acetate Molecular Magnets Anchored at Surfaces

Klaus Kern, Stephan Rauschenbach, Markus Ternes, Gordon Rinke

The high intrinsic spin and long spin relaxation time of manganese-12-acetate (Mn-12) makes it an archetypical single molecular magnet. While these characteristics have been measured on bulk samples, questions remain whether the magnetic properties replica ...

Spin filtering neutrons with a proton target dynamically polarized using photo-excited triplet states

Tim Rolf Eichhorn

In a test of principle a neutron spin filter has been built, which is based on dynamic nuclear polarization (DNP) using photo-excited triplet states. This DNP method has advantages over classical concepts as the requirements for cryogenic equipment and mag ...

Long-Lived States to Monitor Protein Unfolding by Proton NMR

Geoffrey Bodenhausen, Aurélien Bornet, Riddhiman Sarkar, Paul Romeo Vasos, Puneet Ahuja

The relaxation of long-lived states (LLS) corresponds to the slow return to statistical thermal equilibrium between symmetric and antisymmetric proton spin states. This process is remarkably sensitive to the presence of external spins and can be used to ob ...

Lattice symmetries and regular magnetic orders in classical frustrated antiferromagnets

We consider some classical and frustrated lattice spin models with global O(3) spin symmetry. No general analytical method to find a ground state exists when the spin dependence of the Hamiltonian is more than quadratic (i.e., beyond the Heisenberg model) ...
