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...

A new class of materials called Topological Crystalline Insulator(TCI) has been recently proposedtheoretically and subsequently, SnTe has been discovered to exhibit all the...

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...

Our susceptibility studies of the frustrated magnet Yb2Sn2O7 has revealed a spin glass transition of the Yb3+ magnetic lattice at T_g = 140 mK. To our knowledge, this...

Dimensionality plays an important role in determining the anomalous non-Fermi liquid properties in heavy fermion systems. So far most heavy fermion compounds are...

Layered superconductors have been attracted substantial attention since the discovery of the cuprate and Fe-based high-Tc superconductors due to the diversity in their crystal...

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...

Topological insulators are exotic field of study because of presence of fully gapped bulk states and gap less surface states protected by Time Reversal Symmetry (TRS)....

We propose to study two phases of Na-NH3 intercalated FeSe which have distinct values of Tc, both close to 40 K, but different concentrations of NH3 and quite distinct crystal...

The discovery of unconventional superconductivity (SC) in several heavy fermion (HF) compounds has attracted considerable attention. Recently we have investigated CeTSi3 (T=Rh...

We seek to continue our study of CsNiCl3 to determine the nature of the two magnetic transitions.Previous experiments at PSI have shown there are two distinct muons sites, one...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

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...

The investigation of electron correlations in intermetallic alloys is fascinating. At times, depending on the nature and strength of correlations, the compounds exhibit...

Muon spin relaxation will be used to study the low temperature magnetic properties of a new metal-oxalato-framework compound [(C2H5)3NH]2Cu2(C2O4)3. This has a three-dimensional...

This is a continuation proposal, for work carried out previously on the EMU and MuSR spectrometers. We have determined that spin fluctuations are present in this system, by...

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...

We plan to perform transverse field and zero-field μSR experiments to investigate the temperature dependence of the relaxation rate in the superconducting phase of...

The quasi-2-dimensional organic superconductor lambda-(BETS)2GaCl4 is one of the key materials in strongly correlated systems because of the distinct geometrical structure of...
