Exotic finite-temperature collective excitations beyond standard Landau Fermi liquid framework exhibit anomalous temperature dependences in the transport and thermodynamic...

We would like to investigate polycrystalline CaFe2O4 which undergoes two magnetic transitions to a B phase below 190 K and to a A phase below 160 K. Both phases coexist in a...

A2BB’O6 double perovskites are an important family of materials, with spintronic properties found in some examples e.g. Sr2FeMoO6. Although A2+ sites are usually occupied by...

The compound proposed for this study is an interesting example of how strongly spectroscopic properties of pyrene derivatives in the solid state can depend on the crystal...

The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...

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...

Quantum spin liquids (QSL) are new and exotic states of matter that in 2 dimensions were proposed by Anderson to underpin the transition to unconventional superconductivity of...

The magnetism of double perovskites can be amazingly sensitive to subtle distortions of their structures. Previous studies have shown that Ca2NiOsO6 is a ferrimagnet, Sr2NiOsO6...

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...

Ba3BiIr2O9 and Ba3BiRu2O9 undergo very unusual structural transitions at 74 and 176 K respectively, with instantaneous negative thermal expansion of up to 1% in the Ir compound....

The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of...

The interplay between spin, charge, orbital, and lattice degrees of freedoms in SrMn1-xWxO3 (X= 0.1625, 0.175) produce the charge and/or spin density waves (CDW, SDW) modulated...

Multiferroics and in particular BiFeO3 have recieved alot of interest. The potential of multiferroic materials to be incorporated into many devices such as sensors and memory...

We request 6 days on IRIS to study the diffusion of adsorbed gas molecules (H2, CH4, C2H2, C2H4, C2H6) within a functional porous metal-organic framework (MOF) as a function of...

Improper-ferroelectrics (FE) are the backbone to development towards room-temperature multiferroics and carry the immense technological potential for next-generation...

Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In...

Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical...

Recently, we have demonstrated that a large ferromagnetic moment can be induced at theinsulating barrier (La0.3Ca0.7MnO3 (LC7MO)) separating two...

YbAl3C3 undergoes a structural phase transition at 80 K and a spin-dimer formation below 10K. To gain more information on the nature of the spin-dimer state and the phase...

Increasing the density of hydrogen storage is critical for the commercial introduction of hydrogen vehicles. Our nanostructured electrospun ammonia borane (AB)-polystyrene (PS)...
