One of the technological goals is to create materials that show high permittivity and low dielectric loss, which has been achieved by the co-doping of Nb and In into rutile...

Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation...

Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...

: Recently it has been reported from specific heat, resistivity, and susceptibility measurements that CeRh2Ga exhibits very interesting NFL behaviour. The specific heat divided...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...

This is an extention of the previous proposal (RB920385), which was awarded 7 days.The experiment has not been performed yet (scheduled in November), but we forsee...

Noncentrosymmetric superconductors have been identified as good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...

In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...

This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum antiferromagnets. A canonical model system is the spin-1/2 triangular...

NaTiO2 has been predicted to have a variety of unusual magnetic states, depending sensitively on the details of the crystal structure and interaction strength between the...

By the virtue of having an entangled ground state the Heisenberg spin ½ chain systems provide a suitable perform to test multi-qubit quantum information protocols. There have...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new...

Lead iron niobate, PbFe${1/2}$Nb${1/2}$O$_{3}$ (PFN), is a multiferroic material exhibiting paraelectric to ferroelectric and paramagnetic to G-type antiferromagnetic...

Recent progress in the field of molecular magnetism has shown the clear potential for gaining control over the structural building blocks of molecular materials in order to...

We aim to perform zero and longitudinal field muon spin relaxation measurements in order to investigate anomalous spin dynamics effects observed in EuFe2(As1-xPx)2 with x=0.20...

Spin ladders are excellent model systems for studying quantum phase transitions, as they exhibit a quantum critical point between non-magnetic spin singlet dimers to Néel...

We request four days of beam time to conduct zero, transverse, and longitudinal field measurements on pyrochlore iridates A2Ir2O7 (A-227) with A = Yb, Y, Nd in the temperature...

Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen stoichiometry. Most...
