This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...

Recent investigations of physical properties of ACo2As2 (A = Ca, Sr, Ba) indicate that Co-based arsenides could be a potential parent compound like the parent AFe2As2. While...

After the discovery of multiband superconductivity in MgB2 (Tc = 39.7 K) a number of studies have been made to understand the origin of superconductivity in this compound as...

The discovery of superconductivity in ThCr2Si2 type tetragonal Fe-based compounds (i.e. YFe2Ge2) have generated considerable interest. Recently we found bulk superconductivity...

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...

This proposal plans to investigate the destruction of superconductivity by inter-band scattering in Lu_2Fe_3Si_5 doped by Y and Dy. Recent muon spin rotation studies have shown...

In some materials, the onset of superconductivity is accompanied by the spontaneous appearance of small magnetic fields. This is a signature of broken time-reversal-symmetry...

In rare-earth containing metals, there is a strong competition between the tendency of these systems to magnetically order or form a superconducting state, mirroring in many...

PrOs4Sb12 is a 1.85 K superconductor. Its superconductivity shows unconventional behavior, and the originating mechanism remains unknown. One characteristic is an internal...

Ternary compounds R5T4X10 crystallizing in primitive tetragonal structure (space group P4/mbm) present interesting physical properties. Of particular interests are the...

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using...

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...

LuPdBi, a ternary half-Heusler compound, is superconducting at 1.7 K and has an upper critical field of 2.2 T. Specific heat data suggests that superconductivity of LuPdBi is...

Nb0.25Bi2Se3 is a topological superconductor with a transition temperature of 3.5 K and host zero energy Bogoliubov quasiparticles that mimic Majorana Fermions. In Nb0.25Bi2Se3...

Understanding superconductivity has been a goal of condensed matter scientists since its discovery. However, there has been a continual discovery of new materials that challenge...

A series of cyanide-bridged molecular magnets incorporating chiral ligands will be invstigated using muon spin relaxation. The magnets combine Ni(II) with M(III) (M=Fe,Cr,Co)....

Ho2Ir2O7 has a cubic pyrochlore structure. Trigonal crystal fields at both the Ho and Ir sites create Ising-like moments that can order in a non-collinear arrangement with...
