We propose to measure spin waves in detwinned SrFe2As2, combined with our data on detwinned BaFe2As2 this allows us to understand if magnetic excitations in the two systems can...

In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist...

The rare-earth frustrated magnets with dipole-octupole doublet trigger intense research interests due to their exotic quantum phases including spin fragmentation. The newly...

We propose to study the temperature evolution of magnetic excitations in optimal doped Ba0.67K0.33Fe2As2, this work will complement our earlier work on the samples at base...

The discovery of unconventional superconductivity (SC) in several heavy fermion (HF) compounds has attracted considerable attention. Recently we have investigated CeTSi3 (T=Rh...

Heavy fermion compounds with a small energy gap opening in the strongly hybridised 4f-band at EF are currently under intensive investigations. Recently some of us have...

Considerable effort is currently given to investigate proton conducting electrolyte materials for intermediate temperature range (200-500 °C) fuel cells (ITFCs). This proposal...

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...

Recently the coexistence of superconductivity (SC) and antiferromagnetic (AFM) ordering has been reported in CeNi0.8Bi2 with TSC = 4.2 K and TN =5 K, which crystallises in the...

Similar magnetic excitations have been observed in high-transition-temperature (high-Tc) cuprates by time-of-flight neutron spectrometer, namely, a characteristic hourglass-like...

The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored...

We aim to use total scattering and pair distribution function (PDF) analysis to determine the local structure of the disordered amide-borohydride, Na2BH4NH2. We wish to...

The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties...

The relationship between spin fluctuations and superconductivity is an important issue in condensed matter physics. Part of evidence suggesting direct correlation between spin...

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...

We request five days on TOSCA to study the partial phonon density of states of ammonia absorbed within two zeolitic materials. This work is a continuation of our previous INS...

To determine the crystal fields of hexagonal RRh3 (R=Pr, Nd) compounds showing ferromagnetic transitions at TC=3 and 6 K, respectively, we plan to perform inelastic neutron...

Acceptor-doped perovskite oxides exhibit significant proton conductivity under humid or hydrogen containing atmosphere, which opens a unique possibility to be used as...

We aim at studying proximity effects between a ferromagnetic thin film (either metallic or insulating) and a topological insulator (either undoped, or magnetically homogeneously...

Lu and Ho counterparts of RE3Fe5O12 will be an appropriate platform to reveal the complexmagnetic ground state of rare earth iron garnets with common formula RE3Fe5O12. Lu3+...
