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...

Most of Nd-pyrochlores show all-in-all-out long-ranged order ground state at low temperatures. Recently unconventional slow spin dynamics are reported in the paramagnetic state...

Multiferroic materials which exhibit both ferroelectric and (anti)ferromagnetic ordering are of great technological importance offering the potential for the design of novel...

Neutron scattering techniques at the time-of-flight spectrometers at ISIS have shown that there is a well defined excitation with an energy of about 400 meV in YBCO. A similar...

In Ce-based heavy fermion materials, there is competition between the interactions which lead to a magnetically ordered arrangement of the Ce magnetic moments, and the...

To understand the thermal conductivity suppression within PGEC titanate oxide thermoelectrics we hope to complement theoretical calculations performed on several perovskites...

During the past decades, weakly coupled spin cluster systems have attracted much attention due to the possibility of observing concomitantly zero-dimensional quantum and...

We have obtained a LSCOO x = 0.06 single crystal where neutron diffraction shows field induced anti-ferromagnetic order with an onset field in the range 0-1T and increasing...

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...

We have begun an experimental program to investigate the denaturing of DNA, using scattering techniques, to test statistical mechanical models for the moelcule. It is believed...

One of the technological goals is to create materials that show high permittivity and low dielectric loss, which has been achieved by the co-doping of Nb and In into rutile...

Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation...

One of the technological goals is to create materials that show high permittivity and low dielectric loss, which has been achieved by the co-doping of Nb and In into rutile...

Superconductivity with Tc=33 K has been reported in alkali-doped polyaromatic hydrocarbons (PAHs). The compositions and structures are unknown owing to the multiphase nature and...

Most of Nd-pyrochlores show all-in-all-out long-ranged order ground state at low temperatures. Nd2Zr2O7 reveals magnetic fragmentation in the spin ice state, and its...

The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions....

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...

We have prepared a new family of electron-doped oxypnictides \RFeF\ with the same average Rare Earth radius as that yielding the highest superconducting Tc to date, i.e. the...
