Magnetic equiatomic alloys (MEAs) of the general formula MM'X (M, M' = transition metals, X = Si, Ge, Sn) undergo magnetostructural transition of martensitic type on cooling...

We propose elastic neutron powder diffraction experiments on new perovskite antimonates (Ba,K)SbO3. Recently, we confirmed that heavily K doped antimonates become...

Protamines are cationic antimicrobial peptides found commonly in the sperm cells of fish such as herring and salmon that are particularly active against food-borne Gram-negative...

Frustrated magnetic materials are interesting because they show unusual behaviour arising from a near-degeneracy of ground states. The magnetic order of MgCr2O4 - apparently...

We propose to test new apparatus for the magnetic neutron diffraction under uniaxial pressure on WISH diffractometer. The main feature of our apparatus is that the sample is not...

The aim of the experiment is to characterize the magnetic structure of the compound Ce2Ni12As7 using neutron diffraction. At low temperatures the magnetic moments of the cerium...

Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...

This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming...

This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming...

The study of novel manganites, where the tailoring of the Mn formal valence state on the B site is done by the ordering of different cations on the A site of the ABO3 (B:Mn)...

New manganese-based double perovskites Mn2-xCaxFeReO6 have been synthesised at high pressure. Mn2FeReO6 has spin-active cations at all sites; S = 5/2 Mn2+, S = 5/2 Fe3+ and S =...

We propose to perform neutron diffraction experiments on powder samples of possible spin-induced multiferroic materials, 114CdMn7O12 and SrMn7O12, at ambient pressure and low...

This proposal is concerned with the structural study of anionic and cationic surfactant mixture on a charged metal oxide surface using neutron reflectivity. Also to evaluate the...

The compound CeRh2Al10 is a new member of the 1:2:10 stoichiometry series. Previously the three well-studied compounds CeT2Al10 (T=Fe, Ru, Os) were showed to be the first Kondo...

MoTe2 is a “type-II” Weyl semimetal and very topical field of research for both theoreticians and experimentalists. Two weeks ago we measured this system using muSR technique...

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

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...

The magnetoelectric Y-type hexaferrites demonstrate coupling between magnetism and electric polarisation in relatively small applied magnetic fields, and are hence candidate...

Research into the quadruple perovskite manganites has expanded, owing to recent discoveries of technologically relevant properties and entirely novel electronic states. Through...
