Crystallographic and Magnetic structures of PrMn7O12
The study of novel manganites, where the tailoring of the Mn formal valence state on the B site is done by the ordering of different cations on the A site of the ABO3 (B:Mn)... -
Neutron diffraction study of crystal structures and magnetism in PbRuO3 perov...
We have synthesised the ill characterised perovskite PbRuO3 at high pressure and temperature. Synchrotron powder x-ray diffraction shows the room temperature structure to be... -
Study of vibron quasibound state in RAg1-xCuxAl3, 0<x<1 (R=Ce and La) through...
We propouse the study of crystal-field or vibron excitations along the series RAgxCu1-xAl3 (R=Ce and La, 0<x<1), where we expect to studing two main aspects. The first one... -
In Situ Measurement of the Spin Seebeck Effect
The spin Seebeck effect (SSE) is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric generators. The... -
Identification and spin dynamics of state III in phthalocyanines
This experiment proposes to measure the MuSR signal in undoped phthalocyanine (Pc) samples of NiPc, PbPc, FePc and TiOPc, in order to clarify the existence of the paramagnetic... -

Non-local electrodynamics effect in an ¿extreme¿ low-k superconductor
We intend to perform accurate measurements of the magnetic field profile in the Meissner state of an ¿extreme¿ low-k superconductor (In, k = 0.06, k is the Ginzburg-Landau... -
High-pressure and variable-temperature studies of RDX
Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be... -
A µSR study of the charge density wave superconductor CuxTiSe2.
Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and... -
Thermal ionization of bond-centred muonium in diamond
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...
