Understanding the thermal conductivity of zinc oxide is of central importance in assessing its potential for a wide variety of applications in optoelectronics, power electronics...

Methylammonium lead iodide (MAPI) is one the most promising materials for photovoltaics. Notwithstanding the above, access to its phase diagram and the underlying structural...

Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

The compounds we want to study belong to the well-known tetragonal RM2X2 family (R: rare earth, M: d element, X: Ge, Si). In EuCu2(SixGe1-x)2, the Eu valence changes, as a...

We have synthesised the series of lanthanide complexes Ln(trensal-thiophene), where Ln = Er, Dy, Yb and H3trensal = 2,2’,2”-tris(salicylideneimino)trimethylamine. These...

Coupling ferromagnatism and ferroelectriocity in a single phase material at or near room temperature has significant potential for the development of hybrid memory combining the...

Rare-earth (A= La, Ce, Nd, Pr) orthochromites (A CrO3) and orthomanganites (A MnO3) are of interest due to the number of unusual physical properties they possess, displaying...

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...

Currently, we are reaching capacity limits in conventional Si-based memory devices, due to restrictions on further miniaturization. The concept of antiferromagnetic spin...

A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound...

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

Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal...

Cs2CuCl4 has been extensively studied using neutron scattering, and has revealed a quantum spin liquid phase below 2.8 K with antiferromagnetic interactions, and long range...

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

Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This...

We propose to probe the development of the low-temperature magnetism in SrHo2O4 using a high count rate diffractometer such as WISH or GEM. SrHo2O4 belongs to a family of...

We propose to test new apparatus for the magnetic neutron diffraction under uniaxial pressure on WISH diffractometer. The main feature of our apparatus is that the sample is not...

Praseodymium-based cubic compounds with a 4f2 configuration have attracted much attention. In case the crystalline electric field ground state is a nonmagnetic doublet, the...

Honeycomb magnets with strong spin-orbit coupling (SOC) are expect to produce exotic magnetic ground states as exemplified by d5 iridates with Jeff = 1/2 state. In d4 case, SOC...

We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it...
