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

Highly oxidized iron oxides such as SrFe4+O3, CaFe4+O3, and CaCu3Fe4O12 display unusual electronic and magnetic behaviors due to the highly covalent nature of the Fe-O...

Zeolites are porous crystals that make it possible to generate regularly arrayed alkali-metal nanoclusters. Potassium clusters arrayed in zeolite A show ferromagnetism below 7 K...

Using high-temperature high-pressure synthetic methods we have recently prepared the new quadruple perovskite CaFe3Ti4O12. Curie-Weiss magnetic susceptibility and Mossbauer data...

A prototypical frustrated magnet in which structural disorder plays a key role is SrCr9pGa12−9pO19 (SCGO). It is postulated that structurally ordered SCGO hosts a...

Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect (MVE) in...

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

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

Quantum critically is a unifying theme across correlated electron physics. Classical or thermal phase transitions occur at nonzero temperature and are driven by thermal...

Exchange bias (EB) effect, characterized by a shift of the hysteresis loop along the magnetic field axis, has attracted considerable attention because of its significance in...

We request 2 days on GEM to determine the structure of crystalline Li(MeNH2)4: we will be preparing the fully deuterated analogue. Our investigations into the magnetic state of...

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 perovskite-like family of ammonium formate frameworks AB(HCO2)3, where A is a divalent metal ion and B is an (alkyl)ammonium or guanadinium, is of great interest for its...

Magnetic equiatomic alloys (MEAs) of the general formula MM'X (M, M' = transition metals, X = Si, Ge, Sn) undergo magnetostructural transition of martensitic type on cooling...

This is a proposal to determine the magnetic structures of the Rb/NH3 and K/NH3 intercalates of FeSe. These compounds exhibit superconductivity when freshly prepared, but...

One of the major themes in solid-state physics is the realisation of exotic types of relativistic electrons which travel at speeds much slower than the speed of light. These...

With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously...

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...

Metal-organic framework materials are a family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these materials show...

Multiferroic materials, where there is a strong coupling between magnetic and electric order parameters, offer a route to novel voltage-controlled spintronics. Y-type...
