Non-centrosymmetric superconductors (NCS) are believed to be good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...

We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal...

In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric...

The aim of this proposal is to determine the crystal structure of Fe3O4 (magnetite) in its low temperature phase below the Verwey transition. Despite a considerable amount of...

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 solution of the Anderson lattice model (ALM) leads to two renormalized bands near EF with an energy gap due to hybridization between the 4f- and conduction electrons. The...

Several non-centrosymmetric heavy-fermion compounds have been reported to exhibit unconventional superconductivity (SC). For example, both CeRhSi3 and CeIrSi3 order...

The number of Type I binary of ternary alloys is small. Recently, YbSb2 is reported to be a type I superconductor. However, it has an unusual phase diagram, which might show a...

Noncentrosymmetric superconductors have been identified as good candidates for unconventional superconductivity. In particular there is the possibility of Cooper pairs with...

Pure Ho2Ti2O7 and Dy2Ti2O7 exhibit spin ice behaviour. The recent discovery of monopoles and "magnetricity" in Dy2Ti2O7 spin ice has only added to the interest in these...

Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through...

Coexistence of magnetic ordering and ferroelectricity in multiferroic materials, especially at high temperatures, is of great technological and fundamental interest. There are...

In SrEr2O4 the magnetic Er ions are linked through a network of triangles and hexagons, where geometrical frustration can arise, provided that some exchange interactions are...

Several non-centrosymmetric heavy-fermion compounds have been reported to exhibit unconventional superconductivity (SC). For example, both CeRhSi3 and CeIrSi3 order...

In this proposal we propose to investigate the detailed superconducting properties of the superconducting compound Re6Zr with the non-centrosymmetric α-Mn structure....

Superconductivity was recently discovered in alpha-phase FeSex with a Tc of 8 K. Selenium can be replaced with Tellurium (FeSe1-xTex) and this results in an increase in Tc to 15...

Evidence of long-range order has been observed in the diffuse neutron scattering data for a single crystal of HoTbTi2O7.A spin ice like pattern and pinch points coexist with the...

We propose to investigate the structure of the new ¿ordered¿ phases within the Bi2Se3-Bi2Te3 phase diagram of the newly discovered Topological Insulators. The bulk properties 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...
