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

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...

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...

FeSe1-xSx is an important model system for investigating the relationship between superconductivity and nematicity. The nematicity can be suppressed systematically by the...

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...

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...

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...

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...

Topological physics was the subject of this year's Nobel Prize for Physics and over forty years after the groundbreaking work of Kosterlitz, Thouless and Haldane, remains an...

The binary ruthenium pnictides RuAs and RuP exhibit metal-insulator (MI) transition below 200 K and 270 K, respectively, and show an evidence of pseudogap formation in their...

Open p-shell anionic mixed-valence compounds have been recently proposed as intriguing model systems for disentangling the complex interplay of charge, lattice, orbital, and...

In this proposal we propose to investigate the superconducting ground state of the non-centrosymmetric superconductor Ru7B3. Controversy exists over the nature of the...
