Recently, superconductivity has been discovered in a number of materials whose lattices lack inversion symmetry, with important implications for the symmetry of the...

Recently a handful of non-centrosymmetric Ce-based HF compounds with general formula CeTX3 (T=transition mental and X=Si or Ge) have been reported to exhibit superconductivity...

We propose to use MERLIN to examine the full magnetic excitation spectrum Chi¿(q,w) of optimally doped Fe based superconductor BaFe1.84Co0.16As2. The primary goal of this...

We intend to perform the magnetic field penetration depth \lambda measurements on theoxygen reduced and Nb-doped SrTiO_3 -- the first oxide superconductors where two-gap...

The The recent discovery of superconductivity in FeAs-containing compounds (often known as the pnictides has provided a great stimulus to experiment and theory in the study of...

The recent discovery of superconductivity in a series of iron pnictide materials has led to the anticipation that they might lead to new insights into the origins of...

The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should...

In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in...

We will examine the magnetic and superconducting properties of these two novel superconducting systems using muon spin rotation and relaxation experiments. Stoichiometric LiFeAs...

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...

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...

Unconventional superconductivity can be induced in the vicinity of quantum critical point as a consequence of suppression of long range magnetic ordering as function of control...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, (La,Ca)FePO and Sr2ScFePO3. The objective...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

This proposal plans to investigate the superconducting ground state of the Heusler superconductors with a superconducting transition of ~2K. Heusler compounds have attracted a...

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...

The recent discovery of superconductivity in a series of iron pnictide materials has provided impetus to the field of new materials discovery. Like in the cuprate...

Since the discovery of the iron-pnictides superconductors most of the efforts has been devoted to the study of the fundamental questions concerning the coexistence of magnetism...

Our previous studies of superconducting LiFeAs derivatives revealed a significant difference in Uemura scaling compared with all other studied pnictides. This experiment is...
