The layered NaMnO2 is challenging as it is an experimental realization of a two-dimensional spin-2, spatially anisotropic triangular lattice, where the interplay of temperature...

We propose the investigation of the magnetic structure in the room temperature magnet SrRu2O6 and its doped variants. Crystallizing in the honeycomb structure, these systems are...

Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of...

Iron tungstate Fe2WO6 attracts increasing interest in two areas of applications due to its photoelectrochemical behaviour. Fe2WO6 can act either as a photocatalyst for...

Understanding the structures of complex materials is key understanding their properties. Here we wish to determine the structure, both atomic and magnetic, of a complex...

We aim to study select samples of hole and electron doped (A,A')(Fe,B)2As2 (A=Ba, Sr, or Ca; A'=Na, K and B=Co, Ni, or Pt) iron pnictides. These materials exhibit robust...

This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

We propose a study of the low temperature magnetic structure of vanadium dioxide (VO2) compounds using long-wavelength neutron diffraction measurements. This study directly...

The proposed 1111 system whose structures are largely underinvestigated exhibits properties with a strong potential for novel properties that complement our knowledge of the...

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

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...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

We will probe the response of the magnetic and crystal structures of layered manganese oxide chalcogenides to the oxidation state and the local coordination environment of Mn....

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...

When isolated spin clusters are weakly coupled to each other, zero-dimensional quantum and three-dimensional collective magnetism concomitantly occur. This is envisioned in the...

This proposal is to probe the structure and magnetic ordering in Sr2CrO2Fe2As2 and Sr2CrO2Co2As2, in order to complete a description of trends in the Cr sublattice magnetic...

Although the systems of choice for the study of electronic correlations have traditionally been 3d transition metal oxides, the interest has recently been extended to 4d and 5d...

This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the...

We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed...
