K2NiF4-type materials have attracted significant interest for a wide range of applications. While perovskite-based Fe oxide fluorides tend not to be thermally stable, e.g....

The excitations of an Ising antiferromagnetic chain have been studied in the past and are known to form either continuous spectrum or Zeeman ladders. Such a system can be...

The microscopic origin of the zigzag magnetic ground state in a honeycomb lattice of the quasi-2D antiferromagnet Na2Co2TeO6 is debatable. The zigzag phase may occur due to (i)...

This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

We propose to use MERLIN to examine the full magnetic excitation spectrum Chi¿(q,w) of optimally doped Fe based superconductor BaFe1.84Co0.16As2. The primary goal of this...

We propouse the study of crystal-field or vibron excitations along the series RAgxCu1-xAl3 (R=Ce and La, 0<x<1), where we expect to studing two main aspects. The first one...

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...

The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within...

This proposal seeks to explore a multiferroic material new to science, that of the antiferroelectric ¿ antiferromagnetic ceramic Bi0.8Nd0.2FeO3. This new class of material is of...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...

The relationship between spin fluctuations and superconductivity is of paramount importance in understanding the iron-based superconductors. We have recently investigated the...

CeIr3Si2 exhibits highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall CEF splitting of the J=5/2 ground multiplet of...

The reaction of LiH with the oxy-chloride Sr3Fe2O5Cl2 initially leads to the topotactic deintercalation of oxide ions and the formation of Sr3Fe2O4Cl2 containing sheets of...

We have recently developed a computational method to accelerate inorganic materials discovery by identifying compositions that are likely to yield new compounds. To demonstrate...

CeBi2 is a new magnetic Weyl heavy fermion compound which demonstrates the Kondo-type behaviour. It undergoes a transition to a complex antiferromagnetic ground state, and on...

In the last 25 years the highest blocking temperature TB achieved for the best performing molecular nanomagnets has only reached few K. The situation has recently changed...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

Following a recently succesfull measurement of the structure of a monolayer of n-butane adsorbed on MgO we wish to perform neutron diffraction measurements of monolayers of...

UPd3 exhibits four antiferroquadrupolar (AFQ) ordered phases below T0=7.6K. We have determined their order parameters using resonant x-ray diffraction. UPd3 has the dhcp crystal...
