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... -
How muons see the motion of negative hydrogen ions in solids
Ions are often diffusing in solids. Among many ions, H+, Li+, Na+, O2-, and F- are known to become mobile at high temperatures in solids and they are used for fuel cells and... -
Investigation of lithium diffusion in spinel Li2NiGe3O8 and N-doped Li3+xV4-x...
We wish to perform muon spectroscopic experiments on materials from two ceramic systems that are of interest for possible solid electrolyte applications in lithium-ion battery... -
Quantum spin liquid ground state in the Co-based triangular antiferromagnet N...
A triangular lattice occupies a special position in the quantum spin-liquid (QSL) physics. Although the triangular-lattice Heisenberg antiferromagnet is known to evade a QSL,... -
Determining the spin gap in TiPO4
We propose to determine the spin gap in TiPO4, to do this we will carry out a zero-field temperature scan from 5 to 150 K and anticipate focusing our measurements on the region... -
Isotope dependence of the Néel Temperature in cuprates
The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent... -
Interaction of muonium centres and excess carriers in highly injected silicon
We have developed a method to measure carrier recombination lifetime in crystalline silicon with the photo-muSR technique. The key of the method is to measure the dependence of... -
Magnetic properties of yttrium diluted Ho2-xYxTi2O7 spin ice.
Pure Ho2Ti2O7 and Dy2Ti2O7 exhibit spin ice behaviour. The recent discovery of monopoles and "magnetricity" in Dy2Ti2O7 spin ice has only added to the interest in these... -
Frustration-stabilized skyrmions in centrosymmetric compounds
Skyrmions are chiral magnetic spin textures that exist in a variety of different magnetic materials. Skyrmions are usually stabilized in noncentrosymmetric chiral materials by... -
Fluctuating stripes in an insulating hole-doped antiferromagnet
In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped... -
Spin Dynamics in Organic-Inorganie Hybrid Systems
The organic-inorganic hybrid systems consist of organic and inorganic components forming a 2 D layered structure. The distance between adjacent magnetic layers is quite far,... -
Searching for the weak ferromagnetism in cobalt and manganese doped TiO2
Diluted magnetic semiconductors offer the possibility of adding the spin degree of freedom to the electrical and optical semiconducting devices that underpin modern technology.... -
Searching for magnetic ordering and spin-gapped behavior in the first S = 1 ¿...
We propose to explore the spin dynamics in LiNiVO4, a system which we believe is a previously unobserved realization of a random distribution of 1D antiferromagnetic Heisenberg... -
Possible muon diffusion in frustrated magnets
Recent investigations into spin ice suggest excitations that behave like magnetic monopoles, this has included a transverse field muon experiment. When zero field muon... -
Mechanical disorder-induced quantum spin liquid in a two-dimensional triangul...
The quantum spin liquid (QSL) state is one of the possible outcomes of quantum fluctuations advancing magnetic systems into a disordered phase. After more than 30 years of quest... -
Investigating trends in lithium diffusion in doped LiFePO4 materials
There is widespread interest in the development of lithium-ion batteries (LIBs) for rechargeable applications, as they currently offer the highest energy density (amount of... -
MuSR Study of Magnetically Frustrated Lu2Mo2(O,N)7 pyrochlores
The combination of magnetic frustration and low magnetic moment leads to non-classical magnetic behaviour such as spin liquid states. We have prepared polycrystalline samples of... -
Analysis of magnetic properties via the F-mu-F state in inorganic flourides
Here we propose to investigate the fluroide containing compounds - AgF2, CuF2 and Cs2CuF4. By taking advantage of the F-mu-F coupling wich occurs in these compounds, we will... -
Repolarization of Radicals in Liquids
The recovery of the muon polarization in a longitudinal magnetic field has been used to obtain the muon hfcs of organic radicals. In pure benzene there is a single step in the... -
Magnetic ordering and correlation phenomena in the rare-earth RT2Al10 compounds
RT2Al10 is a new series of rare-earth-based ternary aluminide compounds that show a variety of magnetic phenomena. This proposal is for a muSR study on three of its members to...
