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

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

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...

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

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...

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...

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...

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

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

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

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...

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...

We will carry out a definitive local structure investigation of the ferroelectric transition in [ND4][Zn(DCOO)3]. This compound is seen as the canonical example of a...

The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have...

The interplay between orbital order and magnetism in insulating manganites has been extensively studied following the seminal neutron diffraction experiments of Wollan and...

This proposal is to measure the evolution of the magnetic structures of a series of iron oxide chalcogenides and compare the structures as a function of cation sizes and with...

Unconventional superconductivity has recently been suggested in the new class of iron-based superconductors in which unusual gap symmetries have been observed together with...

Ni-Mn based Heusler alloys with composition related to the stoichiometry Ni2MnX, with X belonging to the IIIA-VA chemical species, are widely considered as a class of...

Hexaferrites are well known for their applications as permanent magnet and memory devices. In recent years, the interest in hexaferrite has grown from the point of view of...

This proposal requests time to investigate the influence of an applied magnetic field on the oxyselenide Pr2O2Fe2OSe2. A metamagnetic transition involving ordering of Pr3+...
