Spins arranged on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. In this context, the three-dimensional analogue of these systems,...

Most of the one dimensional spin chain compounds are antiferromagnetic with a rich magnetic phase diagram due to the magnetic frustration. We have synthesized Ba3CrS5 and...

The unconventional filled skutterudite superconductor, PrPt4Ge12 (Tc~7.9K), was recently discovered, for wihch zero field muon spin relaxation (ZF-MuSR) experiments reveal that...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

We have prepared a new family of electron-doped oxypnictides \RFeF\ with the same average Rare Earth radius as that yielding the highest superconducting Tc to date, i.e. the...

Recently we have investigated the cubic compound PrRhSn3 using the dc and ac susceptibilities and the heat capacity. We found an evidence for the cluster-glass behavior with a...

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

The study of spin-lattice relaxation in mononuclear lanthanide complexes is justified by the potential applications of these so-called single-molecule magnets in quantum...

With the observations of spin ice behaviour in Dy2Ti2O7 and Ho2Ti2O7 the rare earth pyrochlores R2B2O7 have evolved as a hot topic of current research activities. In our effort...

The Shastry-Sutherland lattice (SSL) can be described as a 2D square lattice built up from a network of dimers disposed orthogonally and has been observed in SrCu2(BO2)3....

There has recently been a great deal of interest in noncentrosymmetric superconductors (NCS) due to the complex nature of their superconducting properties. The lack of inversion...

A randomly diluted ferromagnet has its transition temperature Tc suppressed to a quantum critical point. Between the Tc of the diluted material and that of the undiluted...

Magnetic order is a property of crystalline materials which contain systems of coupled magnetic moments. In materials known as geometrically frustrated magnets there exist...

The iron-based superconductor LiFeAs exhibits a number of unique features distinguishing it from other materials in its class. As yet, these differences are unexplained. This...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

Nonmagnetic impurity substitutions impact on superconducting properties in various ways depending on the pair-breaking mechanism. The aim of the proposed experiment is to...

This proposal looks to study the electron spin relaxation using high field ALC measurements in two polymers, which differ only by the non-metal (i.e S or Se) in the polymer...

Time reversal symmetry (TRS) breaking in a superconductor is often taken as evidence of unconventional pairing states. The recent observation of TRS breaking in several...

Cs3C60 is driven to a bulk superconductor without symmetry change by the application of pressure. Tc passes through a maximum of 38 K at 6 kbar. We have recently isolated the...

We request four days of beam time to conduct zero and longitudinal field measurements on iridate pyrochlores A2Ir2O7 (A = Y, Lu, Nd) in the temperature range 200 K to 2 K and in...
