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

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...

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

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...

Spin-trimer chain systems are of current interest due to unconventional properties arising from the strong quantum fluctuations and topology, such as the occurrence of 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...

Geometrically frustrated lanthanide gallium garnets find practical applications as low temperature magnetocalorics, but the competing interactions in these materials may give...

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

Several members of the AA'3Mn4O12 quadruple perovskite family have now been realised, and are known to support intricate charge, orbital, and magnetic ordering phenomena. In...

Geometrically frustrated antiferromagnet LuBaCo4O7 exhibits unusual competition between two low-temperature phases with orthorhombic and monoclinic symmetry. Depending on...

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 =...

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...

The A2B¿B¿¿O6 double perovskites consist of an ordered rocksalt arrangement of the B site ions and exhibit a range of different electronic and magnetic properties. Materials...

In this proposal we request time on WISH to study the crystal structure and long range magnetic order on cooling, and the short range magnetic order above TN in an unusual iron...

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

Emerging technologies require increasingly unusual functional materials and so understanding the origins of complex magnetic and electronic behaviour, and how these can be...

Our recent neutron study showed that CaMnFeReO6 has a recently discovered ‘double double perovskite’ structure type with cations ordered across 3 distinct A-sites in columns...

PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu2+ ions coupled by 3 interactions. The 1st neighbor interaction couples Cu2+ into isolated triangles, 2nd nearest...

Special attention has been devoted to the honeycomb iridates (Na, Li)2IrO3, in which SOC, intrinsic geometric frustration, and other competing interactions favor a highly...

Encouraged by many unconventional magnetic properties in the magnetically frustrated spin-chain compounds of the type A3MM'O6, we have recently synthesized a new member...
