Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of...

Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the...

Rcently the NFL behaviour near an antiferromagnetic quantum critical point (AFQCP) has been investigated extensively. Very recently, we have investigated, for the first time,...

NaxC60 and LixC60 are wide theoretically studied systems for hydrogen storage. We recently investigated the hydrogen absorption/desorption of Na10C60 and we found that up to 3.5...

There is much debate about muon stopping sites within materials and in many cases knowing where the muon stops is crucial to understanding the physical properties of different...

In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most...

The recently superconductivity in a quasi-one-dimensional (Q1D) crystal structure, A2Cr3As3 (R=K, Rb and Cs), have been intensively investigated both experimentally and...

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...

Single-Molecular Magnets (SMMs) provide access to the mesoscopic world. They possess slow magnetization relaxation due to an energy barrier induced by axial magnetic anisotropy,...

LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as...

Experimentally exploring the fascinating physics of one- and two-dimensional magnetism continues to rely on the synthesis of novel, model systems with highly anisotropic...

Ni2Mn1+pZ1-p (Z= In, Sn, Sb and < p 1) based ferromagnetic shape memory alloys (FSMAs) with Heusler type structure are fascinating materials as far as the magneto-functional...

We propose to characterise selected radical structures of the green-tea anti-oxidant flavenoid EGCG (& selected analogues), by DFT/post-HF computation and ALC-MuSR, towards...

In order to detect oxygen diffusion in electrolyte materials in Solid Oxide Fuel Cells, we here want to propose a muSR experiment on three oxide electrolytes exhibitng good...

We measure electron-hole recombination rate in low-temperature pure silicon using the photo-MuSR technique. The previous works have measured the recombination rate down to -30...

This experiment aims at studying the magnetic behaviour of the molecular square complex {[Fe{B(pz)_4}(CN)_3]_2[Co(bik)_2]_2}(ClO_4)_2 . 3H_2O [B(pz)_4 = tetrapyrazolylborate,...

Our ongoing project to characterise radical scavenging by the green tea anti-oxidant EGCG and its D-ring analogue, (3,4,5-(OH)3-Bz) is near-complete. ALC-MuSR experiments on the...

The intermetallic alloys RNiAl and RCuAl have been of high interest for several years. They crystallize in the hexagonal structure (ZrNiAl-type) and form various and complicated...

Recent work has revealed that metal-organic frameworks (MOFs) can also exhibit this multiferroicity. These materials are particularly interesting since their structures are...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...
