There has been a great deal of interest in non-centrosymmetric superconductivity, mainly induced by the discovery of CePt3Si. The presence or lack of inversion has important...

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...

The intermetallic alloys RNiAl and RCuAl have been of high interest for several years. They crystallize in the hexagonal structure (ZrNiAl-type) and form various and complicated...

RE2Fe3Si5 are unusual superconducting systems, with coexistence of magnetism on the RE site with superconductivity ( the Fe does not support a magnetic moment). Of particular...

In this proposal we propose to continue our investigation into the LaNiC2 non-centrosymmetric superconductors. Previously, we have shown that in this system time reversal...

We propose to investigate the spin fluctuations in a candidate S=5/2 Kagome lattice. Previous neutron diffraction has found that RbFe2F6 maybe a good realization of a Kagome...

We propose to investigate the detailed superconducting properties of the non-centrosymmetric ternary silicides MRSi (where M=Nb, Ta R=Re, Ru). We plan to investigate the vortex...

Metal oxides(MO) are widely used in technological applications especially for catalysts and supports for catalysts. We propose to use the inelastic response of H2 adsorbed on...

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...

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...

Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of...

The quantum spin liquid (QSL) is a long-standing attractive topic in condensed matter physics due to its tight relation to exotic properties such as high temperature...

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...

RMnAsO (R = Ce and La) are isostructural compounds with Fe-based oxypnictides, but has a unique properties as Mott insulator unlike the nonsuperconducting parent compounds of...

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...

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...

The quantum spin liquid (QSL) state is one of the possible outcomes of quantum fluctuations advancing magnetic systems into a disordered phase. After more than 30 years of quest...
