Dilution of the Near-Kagome Compound Vesignieite
Vesignieite, Cu3VBa2O8(OH)2, is one of very few materials approximating a kagome spin-1/2 Heisenberg antiferromagnet, a model that is the ideal setting for novel quantum spin... -
The Crossover Between Giant Magnetoresistance and Superconductivity in RuSr2G...
Giant magnetoresistance (GMR) is observed up to -49% in RuSr2R1.8-xY0.2CexCu2O10-d ruthenocuprates. The magnetotransport is very sensitive to lattice effects. As , the mean A... -

Search for magnetic long-range order in a spin-liquid candidate K2Ni2(SO4)3
We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence... -
Probing Magnetic Order in Defective Reduced Graphene Oxides by Means of mu-SR
Reduced graphene oxide (rGO) with defective structure has shown interesting magnetic properties in the frame of room temperature ferromagnetism. The origin of the magnetic... -
Magnetic order in the low doping regime in La(2-x)SrxCoO4
While investigating the ordering and magnetic dynamics in La2-xSrxCoO4 we found some intriguing behaviour for samples with small x, which would imply that the phase diagram is... -
Motion of Positevely Charged Muonium Centres in Transparent Conducting Oxides
A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and... -
Continuation of the low-frequency fluctuations muSR study in Mn-doped La1-yYy...
The aim of the experiment is to study, in low magnetic fields, the very slow spin fluctuation (MHz range) present in the normal phase of La0.8Y0.2LaFe1-xMnxAsO0.89F0.11... -
Copy of: Field driven quantum phase transition in a Kitaev honeycomb magnet
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... -
Muon spin rotation study on Pr2T3Ge5 (T = Rh and Pd)
Recently we have investigated Pr2Pd3Ge5 and Pr2Rh3Ge5 compounds which form in the orthorhombic structure. Pr2Pd3Ge5 exhibits two magnetic transitions at TN1 = 7.5 K and TN2 =... -

Common d5 pyrochlore iridates, A2Ir2O7 or A2Ir2O6O, are reported to have long range magnetic order based on muSR experiment. Only Pr2Ir2O7 has been identified as a metallic... -
Local magnetism in graphene / transition metal oxide nanocomposites
Properties of graphene that make it an important material are its exceptionally high conductivity, massless fermions and a high velocity of electrons near the Dirac points.... -
Spin dynamics of the zigzag pseudospin-1/2 quantum chain compound PrTiNbO6
One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may... -
Neutron scattering of coke deposits on catalytic samples - MAPS
Catalysts used for water-gas shift reactions, and other important industrial processes, often suffer from deposition of hydrocarbon and carbon species (coking) to reduce their... -
Studies of the new S=1/2 triangular lattice spin liquid kappa-ET2Ag2(CN)3 (CH...
A new member of the class of S=1/2 triangular lattice quantum spin liquids will be studied with muons. It is obtained by replacing Cu with Ag in the original compound... -
Multiple phase transitions in U2Pt2Sn studied with muon-spin-rotation and rel...
U2Pt2Sn crystallizes in the tetragonal Zr3Al2-type structure (P42/mnm, Z = 4), where uranium atoms occupy two different sites. Our measurements of bulk properties have shown... -
Oxygen deficiency in the quantum spin ice Tb2Ti2O7
Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen content. Most... -
Investigating the magnetic ground states in complex manganese based oxides
The geometric frustration, combined with other parameters like the net quantum spin state (1/2, 1 or 3/2) is expected to give rise the exotic magnetic ground states such as the... -
High-Energy dynamics and search for a continuum in CaFe2O4
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...
