We plan to investigate by means of zero-field muSR the doping dependence of the sublatticemagnetization in La2Cu1-xZnxO4 and in La2Cu1-xMgxO4. In both systems Cu2+ S=1/2 spins...

Single-Molecular Magnets (SMMs) provide access to the mesoscopic world. They possess slow magnetization relaxation due to an energy barrier induced by axial magnetic anisotropy,...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...

Skyrmions are topologically protected vortex-like spin textures, and have been attracting increasing attention due to their potential technological applications for spintronics....

The relative importance of factors affecting the low temperature ALC spectra of organic molecular systems such as polymers and small molecules is a topical issue. Polybutadiene...

We propose a series of measurements to complete the previous direct spectroscopic measurements of the Muonium defect energy levels in Silicon Carbide (SiC; RB110134). We will...

Nearly all polymers form glasses and the glass transition at temperature Tg dominates many physical properties of polymers that are relevant for their applications. The most...

The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of...

In this proposal, we wish to study the origin of the multiferroic nature in Sr4Fe2(CO3)O6. In the magnetization data, antiferromagnetic (AFM) ordering appears at TN = 340 K and...

This proposal seeks to conduct total-scattering studies on thallium and caesium azides to investigate the effect of temperature on the atomic motions, particularly of the azide...

The extreme quantum nature of muons and muonium in condensed matter is the result of having a mass that is nine times lighter than that of a hydrogen atom. While this quantum...

We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field...

We propose to study the evolution of ZF-muSR and low-field (100 G) TF-muSR spectra and relaxation times across the charge ordering temperature T0 = 140 K of RbFe2As2 iron based...

The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics because the model uniquely provides exactly solvable...

This experiment proposes the continuation of a study, initiated at J-PARC, on a new type of activated carbon material, with a pore structure and chemistry "tunable" in a manner...

Here we propose to use muon spectroscopy to study the diffusion of sodium in hard carbon anode materials of various porosity for sodium ion batteries. Hard carbon is the most...

The study of organic ferroelectrics based on mixed-stack charge-transfer salts is currently a rapidly developing research field. These materials attract interest as highly...

We propose to continue laser spectroscopy measurements of the muonium (Mu-) centres in n-type doped silicon carbide. Scanning a wide wavelength range, and changing the relative...

Magnetic cooling promises efficiency savings at room temperature but requires rapid cycling of a magnetic refrigerant in a magnetic field. Refrigerants with first order...

In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself...
