We propose to obtain the temperature dependence of the diamagnetic spin-precession amplitudes up to 1100 K for the three electrical types of 4H-SiC in order to extract the Mu...

In order to reduce global greenhouse gas emissions, and to meet the UK's commitment of a reduction of 80% by 2050, it is necessary to make major advances in efficient, clean and...

Hydrogen storage is a significant area of energy materials research and there have been extensive efforts into the discovery and development of lightweight materials. Although...

We plan to investigate by means of zero-field muSR the doping dependence of the sublatticemagnetization in La2Cu1-xZnxO4 and in La2Cu1-xMgxO4. In both systems Cu2+ S=1/2 spins...

We would like to propose a continuation experiment on Li-ion battery cathode material, Li(Ni,Co)O2. In previous experiments in 2013 and 2014, we attempted muSR technique to...

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...

Ni-Mn based Heusler alloys with composition related to the stoichiometry Ni2MnX, with X belonging to the IIIA-VA chemical species, are widely considered as a class of...

Here we propose a u+SR investigation on the solid solution Cax-1NaxCr2O4, a Q1D zigzag chain compound where Na+ ions are allocated in the hexagonal one-dimensional channels...

Lithium diffusion in magnetic materials is found to be well detected by muon-spin spectroscopy. However, such a diffusive behavior has been measured without potential gradient,...

Recently there have been many reports on how high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at...

Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. In recent...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...

The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the...

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...

We intend the measure the neutron reflectivity of a purely magnetic interface generated at a ferromagnetic/antiferromagnet phase boundary within an FeRh epilayer, a material...

An all solid state lithium ion battery (SSLIB) has an advantage in electrical capacity compared to the popular lithium ion battery (LIB) using a liquid electrolyte. However, a...

In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD...

CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) is material which exhibits electrical resistive switching at 300K and has two structural forms (I and II), each with very...

Hydrogen storage materials with a low working temperature are strongly required for the application of the next generation on-board hydrogen storage system. Among several...

Since the discovery of the iron-pnictides superconductors most of the efforts has been devoted to the study of the fundamental questions concerning the coexistence of magnetism...
