Recently synthesized new perovskite TlMnO3 is distinct in respect of crystal structure (space group) and orbital ordering from those of the previously known trivalent perovskite...

The aim of the present proposal is to experimentally investigate the magnetic order below Tc in the cubic quasicrystal approximant Au5.027Si1.307Tb, which orders ferro- or...

The multiferroic perovskite BiFeO3 is the only material that displays both ferroelectric and antiferromagnetic order at RT. Significant efforts are aimed at better understanding...

Tetrahedrites are minerals which consist largely of earth-abundant and environmentally-friendly elements (copper and sulfur). This family of materials is attracting much...

A-site ordered quadruple perovskites, AA’3B4O12, show many interesting physical and chemical properties, for example, inter-site charge transfer and disproportionation, giant...

We are interested in a family of double perovskites which have remarkable properties. One member of this family, Pb2CaOsO6, transitions from behaving like a metal to being...

This experiment will probe the evolution of magnetic ordering in compounds with square planar Cr2+ ions in CrO2 oxide layers, and the interaction of these moments with Mn2+ and...

Our aim is to study with high resolution neutron powder diffraction the two orthorhombic phases of Mn2TeO6 at RT, so as to understand the origin of the observed structural...

Materials with the perovskite crystal structure are ubiquitous in condensed matter physics. Despite being known for several years, the quadruple perovskites, which afford...

Within the framework of multifunctional materials showing the presence of both magnetic and electrical properties, the lead¿based double perovskites Pb2BB¿O6 are recognized as...

Osmates in the perovskite-like structure are very topical. For example, recent discoveries include Slater transitions, and "ferroelectric-like" structural transitions. These...

The spin-reorientation phase transition (SRPT) is an interesting phenomenon observed in rare-earth chromates. The test run scattering experiments done using high-resolution,...

Perovskite oxides exhibit a large array of interesting electronic properties. Owing to their difficult synthesis (requiring extremely high pressures) the MOsO3 Osmates offer a...

Multiferroic materials which exhibit both magnetic and electric ordering offer the potential application in data storage, spintronics, and microelectronics. To date the most...

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

The new compound Bi2CoTiO6 is synthesized using high pressure - high temperature techniques. Its properties were characterized by X-ray diffraction, magnetic measurements, and...

We have recently prepared a new strontium ruthenate, SrRu2O6, using hydrothermal chemistry. The material shows magnetic order, probably ferromagnetic, than persists above, and...

Generating pressure above 1GPa for neutron diffraction typically requires the use of a Paris-Edinburgh press. Whilst the presses operate very reliably at ambient temperature,...

We propose to perform neutron diffraction experiments on a powder sample of a multiferroic hexaferrite PbFe12O19. A recent paper has reported room temperature multiferroic...

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