Lead iron niobate, PbFe${1/2}$Nb${1/2}$O$_{3}$ (PFN), is a multiferroic material exhibiting paraelectric to ferroelectric and paramagnetic to G-type antiferromagnetic...

We seek to continue our study of CsNiCl3 to determine the nature of the two magnetic transitions.Previous experiments at PSI have shown there are two distinct muons sites, one...

Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of...

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...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

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...

By the virtue of having an entangled ground state the Heisenberg spin ½ chain systems provide a suitable perform to test multi-qubit quantum information protocols. There have...

NaTiO2 has been predicted to have a variety of unusual magnetic states, depending sensitively on the details of the crystal structure and interaction strength between the...

There is a lot of interest in Li based oxides that show potential to be used within cathode materials in batteries. However, in certain oxides, the addition of magnetic ions can...

Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was...

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,...

The new compound Li3Mg2RuO6 exhibits interesting structural and magnetic properties. The Ru5+ sublattice is intrinsically frustrated : chains, along various [110] directions, of...

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...

This is an extention of the previous proposal (RB920385), which was awarded 7 days.The experiment has not been performed yet (scheduled in November), but we forsee...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...

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...

: Recently it has been reported from specific heat, resistivity, and susceptibility measurements that CeRh2Ga exhibits very interesting NFL behaviour. The specific heat divided...

Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...

Disorder of magnetic cations usually suppresses long-range spin order: the Curie or Néel temperature drops rapidly, and a spin glass state often results at high disorder levels....
