Improper ferroelectricity in hexagonal tungsten bronzes
We address the detailed atomistic mechanism of ferroelectricity in a new family of oxides typified by the composition CsNbW2O9. Contrary to the mechanism in most ferroelectrics,... -
Ferromagnetic fluctuations in Sr2-xLaxRuO4
Theoretically, it was suggested that the p wave superconductivity in Sr2RuO4(Tc=1.5 K) is mediated by the ferromagnetic fluctuations. However, there is still no convincing... -
Probing the Magnetism and Suspected Quantum Fluctuations in Green Dioptase
It has been suggested that within green dipotase there the magnetism is dominated by quantum flucuations but evidence for this is not definitive. This means that in this... -
Muon spin relaxation study of CDW and superconducting states in LaPt2Si2
Coexistence of charge density wave (CDW) and superconductivity (SC) is a long standing puzzle in condensed matter physics. LaPt2Si2 exhibits CDW transition at 112 K followed by... -
Coexistence of superconductivity and magnetism in the half-Heusler compound E...
This half-Heusler compound is also a semi-metal, with a low carrier density and non-trivial topological features. The crystal structure is also non-centrosymmetric, which is... -
Search for spin excitations and spin resonance in ThFeAsN1-xOx (x=0 and 0.3)
Recently, the first nitrogen-containing iron pnictide superconductors ThFeAsN, has been discovered with Tc = 30 K. We have investigated the gap symmetry in ThFeAsN using musr.... -
Magnetic properties of 3D molecular magnet based on Co and Nb ions
We aim to study the 3D molecular magnet {[Co(pyrazole)4]2[Nb(CN)8]} possessing a unique structure, where low connectivity indices support a 3D extended spin network.... -
Spin ordering in strongly geometrically frustrated magnets YCa3(MO)3(BO3)4 (M...
Geometrically frustrated magnetism (GFM) occurs in systems where magnetic cations (spins) are located on a lattice with a triangular geometry and there are antiferromagnetic... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
Molecular dynamics in the Metal-Organic Framework [CH3NH3][Co(COOH)3]
Magnetic hybrid organic-inorganic Perovskites have attracted much attention lately as they potentially show a magneto-electric coupling, thanks to the strong interaction between... -
Spin dynamics in the iron-based superconductor CsCa2Fe4As4F2
The relationship between spin fluctuations and superconductivity is of paramount importance in understanding the iron-based superconductors. We have recently investigated the... -
Chasing the hydrogen-saturated defects in tungsten with Muon spectroscopy
The structure and dynamics of hydrogen (H) defects in tungsten recently become a topic of major interest since this metal has been chosen as shielding material for the next step... -

Radiation Tests with ISIS beam at RAL
The possibility to perform radiation tests of the NA62 integrated trigger and data acquisition board with a beam provided by ISIS Neutron and Muon Source at the STFC RAL is... -
Antiplasticizing effect of water in amorphous prilocaine
In glassforming organic materials, the addition of water usually has a direct plasticizing effect, visible in a lowering of the glass-transition temperature Tg upon hydration of... -
Ferromagnetic ordering in -[Lanthanide(III)-Radical]n- coordination polymers
The molecular magnet [Sm(hfac)3(boaDTDA)]n is the first metal complex of a thiazyl-based neutral radical ligand to exhibit ferromagnetic ordering and was the subject of... -
Magnetic excitations in a spin-liquid candidate K2Ni2(SO4)3
In majority of magnetic compounds interactions between spins, that reside on magnetic ions, result in a long-range ordered state below a critical temperature. In some materials... -
