Obtaining Quantum Critical Signatures of the Spin Liquid Phases in 1T-TaS2
The system 1T-TaS2 is a charge density wave (CDW) insulator below 180 K that has one residual spin 1/2 for every 13 Ta atoms in the modulated CDW structure. These spins and... -
Laser-induced electron transfer in Trp-Tyr
We wish to perform longitudinal field measurements on the dipeptide Trp-Tyr under laserexcitation, to probe the electron transfer process within the molecule. We have already... -
Vibrations of a muoniated radical center and photochemistry in benzophenone
Benzophenone is an ideal material to study vibrations of a muon radical centre with near-IR laser light, as all C=O bonds in solid state are almost parallel to each other and it... -
Excited/Ground State of Kekulé di-radical Material Bisphenalenyl
Kekulé di-radical (KDR) with two radical centers of independent spins has a low-spin ground state (singlet S0 with antiparallel spins), and interestingly high-spin triplets (T1)... -
Searching for magnetic order in two nitronyl nitroxide isomers
Using nitronyl nitroxide radicals it is possible to prepare purely organic ferromagnets without inclusion of any transition metal or lanthanide ions. Muons are uniquely... -
Low Temperature Properties of a Uniform S=1/2 Triangular Lattice System
It is proposed to use TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions that... -

This continuing experiment is proposed based on our previous experiment RB1510208, which we have carried out just recently. The experiment successfully observed the lifetime of... -
Muon states in black phosphorus
Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with... -
