MuSR studies of the magnetic properties of hyperexpanded fullerides close to ...
We have been recently successful in isolating the fcc polymorph of the key hyperexpanded fulleride Cs3C60 - this phase can be driven to a bulk suprconducting state without... -
Quantum spin liquids: beyond Herbertsmithite
We aim at exploring the ground state of new Cu2+ S=1/2 kagome compounds, isomorphic to the now-celebrated Herbertsmithite, namely CdCu3(OH)6Cl2 and MgCu3(OH)6Cl2. Due to the... -
muSR studies of AF/SC/normal phase interplays in La2-xSrxCuO4 and Ba(Fe,Ni)2As2
We propose muSR studies on superfluid density in the overdoped La2-xSrxCuO4 (LSCO). The Hayden group (Bristol) has been growing high-quality LSCO single crystals, and performed... -

INS investigation of post-pressurised Cs2CuCl4
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... -
Penetration depth in isovalent Ru substitution Ba(Fe$_{1-x}$Ru$_x$)$_2$As$_2$
The investigation of the recently discovered high-Tc superconductors based on iron pnictides, has attracted great attention. Much effort has been devoted to determining the... -
Low temperature magnetic order and spin dynamics in Ho2Ir2O7
Ho2Ir2O7 has a cubic pyrochlore structure. Trigonal crystal fields at both the Ho and Ir sites create Ising-like moments that can order in a non-collinear arrangement with... -
Non-collinear Order and Spin Fluctuations in Chiral Cyanide-bridged Molecular...
A series of cyanide-bridged molecular magnets incorporating chiral ligands will be invstigated using muon spin relaxation. The magnets combine Ni(II) with M(III) (M=Fe,Cr,Co).... -
Magnetic Order in the Pyrochlore Phase of Gd2Zr2O7
Along with the titanate and stannate materials, Gadolinium Zirconate, Gd2Zr2O7, makes up a series of model pyrochlore systems characterized by a Heisenberg antiferromagnetic... -
Disorder-induced suppression of magnetic ordering in frustrated Co(1/3-d)NbS2
Magnetic ordering in frustrated systems with large magnetic interactions remains a key question in condensed matter physics. Despite strong theoretical and experimental quest to... -
Magnetism and superconductivity in hyperexpanded fullerides close to the Mott...
The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes... -
Magnetic Charge Transport in Spin Ice
The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored... -
Spin dynamics in the quantum spin ice state of Yb2Ti2O7
We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using... -
Investigating Magnetic Ordering in Ba2MnWO6 and Sr2MnWO6
Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically... -
The internal field in a ferromagnetic organic radical crystal with chiral mol...
Shiomi et al. have prepared a nitronyl nitroxide radical-based compound which has a chiral packing of the molecular units. This is the first discovery of a purely organic chiral... -

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and... -
Probing the spin dynamics in the pseudo-quaternary Y1-xErxNi2B2C compounds
Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and...
