The enhancement of magnetic characteristics of Lu1-xA������xFeO3 (A������ = Sr, Zr, La, Nd) will be investigated in this work. Although substitution effects, in this case, are...

Our proposal is to use neutron total scattering on GEM to study framework flexibility and the phenomenology of the displacive phase transition in the cyanide-containing...

BaTiO3 is the prototypical ferroelectic perovskite and has been well studied for over 60 years. The standard structural picture is that it is cubic and paraelectric at high...

There is a significant interest in the electronic and magnetic properties of the layered iridates owing to the variety of potential exotic phases of matter they exhibit. In...

Magnetoelectric materials, combining properties associated with magnetic and ferroelectric memory applications (e.g. in hard drives) are difficult to prepare but would represent...

Rare-earth orthoferrites (RFeO3) and orthochromates (RCrO3) exhibit canted antiferromagnetic structure with 3 different allowed spin configuration (SC)s.Temperature as well as...

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 =...

Bismuth Ferrite (BiFeO3) is the archetypal multiferroic material and as such has been copiously studied using a wide variety of techniques. Despite this, new structural and...

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has...

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

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

In recent years, there has been a large research interest in noncentrosymmetric systems in part due to the exotic physics these systems display. Examples of chiral magnets...

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

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

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

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

Because of the potential applications of multiferroicity, the discovery of a new multiferroic (MF) material is invariably met with great enthusiasm in the condensed matter...

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...

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...
