Spin liquid properties of the S=1/2 triangular lattice system Li2ZnMo3O8
Thermal, magnetic, neutron and muSR measurements all point towards a gapless or almost gapless spin liquid ground state for the triangular lattice spin system of S=1/2 Mo3... -
Kinetics of Muoniated Radicals Studied With Radio Frequency Muon Spin Resonance
Radio-frequency muon spin resonance is a powerful technique for studying free radicals and their reaction kinetics, but it has not yet been used to study complex reactions in... -
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... -
Muonium in cubic stabilized zirconia
This proposal is part of a long-range program aiming at determining the stable charge-stateconfigurations, site and impurity energy levels (donor and/or acceptor) of hydrogen in... -
Quantum magnetism of the low-dimensional copper carbodiimide CuNCN
Our proposal aims at microscopic investigation of magnetism of the novel copper-based low-dimensional spin system CuNCN, the first compound with a pure nitride environment of... -
ALC spectroscopy of the molecule BEDT-TTF and some of its salts
The electron donor molecule BEDT-TTF (ET) provides a versatile building block for constructing molecular metals, superconductors, magnets and quantum spin liquids. A common... -
characterisation of muonium in functionalized acenes
We wish to measure the high field ALCs of a series of related functionalised acenes, to understand the role of the ligands on the electron spin relaxation, which is of... -
µSR Study to Investigate the Magnetism of Ca3Cu1-xMn1+xO6 (x = 0.07)
Low-dimensional systems exhibit some of the most interesting physical phenomena seen in condensed matter physics. One-dimensional (1D) spin chain is important for understanding... -
Artificial [FeFe]-Hydrogenases and Muon Spectroscopy
Preliminary measurements of [FeFe]-hydrogenase model complexes were made in a previous experiment using EMU (RB 1010177). The results were interpreted in combination with DFT... -
muSR investigation of spin-orbit coupling driven magnetism of Ba3Zn1-xNixIr2O...
Strong spin-orbit coupling (SOC) in 5d transition metal oxides very often leads to unexpectedelectronic and magnetic ground state. While a nonmagnetic J=0 ground state can be... -
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... -
Muon Spin Relaxation and ALC Resonance in Magnetic and non-Magnetic Oxalate S...
Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a... -
Muon level-crossing resonances as a probe for studying antiferromagnets at pu...
We propose a set of measurements using the HiFi spectrometer in which muon level-crossing resonances are used to probe the internal field inside antiferromagnets in which the... -
Hunting for the low-temperature, low-field magnetization plateau in Tb2Ti2O7
Tb2Ti2O7 is a pyrochlore antiferromagnet that has previously been viewed as a spin liquid. This description fails to describe key features of its physics and more recently the... -

We propose to use longitudinal field muon-spin relaxation to investigate the excitation spectrum of the most successful realizations of one- and two-dimensional antiferromagnets... -
Unconventional superconductivity in quasi-1D K_2Cr_3As_3 (QLCR)
Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a... -
RF MuSR in the gas phase: The Search for a Radical State (RB920227)
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
Muon States in Nanostructured Carbonaceous Materials
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... -
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...
