Identification and dynamics of muon states in octabutoxy-phthalocyanine
The current experiment proposes to identify and study the spin dynamics of the muon states formed in octabutoxy-phthalocyanine (oBu-H2Pc) using the avoided level crossing... -
Muon Spin Relaxation studies of Ni2TCNQ, Ni(TCNQ)2 and related materials
Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it... -
Muonium in alpha-boron
Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work... -
End-Game: Cornering Solvent Effects on H-Addition in Green Tea Anti-Oxidants
Our ongoing project to characterise radical scavenging by the green tea anti-oxidant EGCG and its D-ring analogue, (3,4,5-(OH)3-Bz) is near-complete. ALC-MuSR experiments on the... -
Utilising Quadrupolar Level Crossing Resonance to Gain Important Information ...
There is much debate about muon stopping sites within materials and in many cases knowing where the muon stops is crucial to understanding the physical properties of different... -
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... -
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... -
Investigating the muon radical in Sulphur
Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution.... -
ALC muon spectroscopy of antioxidants
In a previous experiment (RB910492) we have made preliminary measurements of the rates of addition of muonium to vitamins C and E, as suggested by the ISIS panel. These rates... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
Understanding the spin-Peierls Transition in KTCNQ and derivatives
Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify...
