Negative muon spin rotation and relaxation for MgB2 at low temperatures
This is a continuation negative-muon spin rotation and relaxation (mu-SR) experiment on MgB2 having a superconducting transition at 39 K. Since positive muons start to diffuse... -
Investigation of magnetic defects in exfoliated and ball-milled graphite
The recent interest in carbon-based materials like graphene stimulated a deeper analysis of the magnetism in graphite defects. In a previous µSR experiment we observed an... -
Fluoride uptake by polyaniline films for water purification and remediation
The beneficial effects of fluoride are well known, but higher levels are dangerous to health. Existing remediation methods used to address the latter situation all have... -
Repolarization of Radicals in Liquids (RB920344)
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... -

Hydrogen impurity in solar cell materials CIGS and CZTS
In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive... -
Superconducting state arising out of a Topological Crystalline Insulator
A new class of materials called Topological Crystalline Insulator(TCI) has been recently proposedtheoretically and subsequently, SnTe has been discovered to exhibit all the... -
Muonium in widegap oxides
This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen... -
Spin dynamics in a doped S=1/2 Heisenberg Antiferromagnetic chain SrCuO2
We propose to microscopically study the role of defects on spin transport in one of the best approximations to the ideal antiferromagnetic Heisenberg s = ½ chain. By measuring... -
Muon spin dynamics in ZnSe
We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is... -
Muonium in BeO
BeO is a promising material in order to improve HfO2-based MOSFET devices, and a candidate substitute of HfO2 as high-k gate material. The electrical properties of BeO can be... -
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... -
Magnetic properties of graphene
Magnetic properties of graphitic compounds are of current interest for both theoretical and experimental research in the fields of condensed matter physics and magnetism. In the... -
ALCs investigation of the polymer PTAA (chain length = 80)
This proposal aims to study the avoided level crossing resonances (ALCs) of the amorphous polymer PTAA, with chain length 80. Previous measurements on PTAA have studied a...
