Recently the discovery of superconductivity in the quasi-1D Rb2Cr3As3 with TC=4.8 K has attracted considerable interest. The unconventional superconductivity has been revealed...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

The discovery of superconductivity in ThCr2Si2 type tetragonal Fe-based compounds (i.e. YFe2Ge2) have generated considerable interest. Recently we found bulk superconductivity...

Recently, barlowite Cu4(OH)6FBr have been attracting much attention as a new kagome system with a Z2 topological order, which may yield spin liquid state at relative high...

In an attempt to study the dynamics of Dy2Ti2O7 measured using muons we have made a sample of 162Dy2Ti2O7 where the 161 and 164 isotopes are reduced to a minimum (max. 0.6% of...

We propose to explore the low temperature magnetic ground state of the nearly ideal honeycomb iridate Ag1.5Li0.5IrO3 to confirm that no magnetic ordering occurs and that the low...

Muon spin relaxation is a remarkably powerful tool for discovering magnetic order in quasi-one-dimensional magnetic chain compounds, particularly when the weak interchain...

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...

Zn-doped barlowite, ZnxCu4-x(OH)6FBr, is a new experimental realisation of an S = 1/2 kagome antiferromagnet in which the ground state may be tuned from a Néel ordered state to...

Bramwell et al. have provided an elegant demonstration of dynamics in magnetic monopoles in spin ice measured by muons implanted inside the sample. However, it is likely that...

Quantum spin liquid (QSL) states emerge when the arrangement of magnetic moments in a material frustrates magnetic interactions and low spin magnetic moments allow for strong...

Quantum spin liquid (QSL) state is a state that spins are highly entangled and frustrated even at absolute zero temperature, which has attracted lots of attentions due to its...

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)....

"Breathing pyrochlores" are a new class of material that contain sublattices of corner sharing tetrahedra, where the the sizes of the tetrahedra differ on the different...

Spin–orbit coupling (SOC) is a fundamental interaction in solids that can induce unusual physical properties, from topologically non-trivial insulating states to unconventional...

Spin ladders are excellent model systems for studying quantum phase transitions, as they exhibit a quantum critical point between non-magnetic spin singlet dimers to Néel...

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...

Spin liquids are magnetic materials with no long range ordering. We would like to explore the magnetic ground state of a Copper based Metal-Organic Framework(MOF) with suspected...

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...

In recent times, Ce based HF compounds have become a promising and active research field in condensed matter physics as one can drive the system towards quantum critical point...
