Our sample of fully oxygenated and de-twinned YBCO has previously given the first measurements of the intrinsic vortex lattice in this material, up to fields of 11 T. We have...

We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the...

Hydrogen chloride exhibits a complex phase diagram account made of its simple molecular structure. Three crystalline phases are known to exist at ambient pressure below its...

The solid solution Mn(1-x)Fe(x)WO4 exhibits complex antiferromagnetic order with coexistence of commensurate and incommensurate magnetic structures. Furthermore, the MnWO4 end...

YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down...

In the last five years, we have carried out a comprehensive study of the family of REMn2O5 multiferroics by neutron and X-ray magnetic scattering, providing details about the...

The formation of silk fibres in both spiders and silkworms is characterized by a conversion of short range ordered structures in solution into long range ordered beta-sheet rich...

The system NaNbO3 ¿ KNbO3 is one of the most widely studied as a ¿green¿ replacement for the piezoelectric material PZT (PbZr1-xTixO3). Despite its enormously growing...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists....

Metal-organic magnets are of interest primarily due to the synthetic versatility enabled by the vast array of organic complexes which can be used to coordinate magnetic ions and...

The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity...

We would like to complete the phase diagram by measuring one more sample of Fe1+xTe for x = 14 %, which represents a point at one extreme of the phase diagram. The simple binary...

BiFeO3 is one of the most widely studied multiferroics (ferroelectric TC ~ 830°C, and antiferromagnetic TN ~ 370°C). Rare earth doping has been shown to be a suitable method of...

This project concerns fundamental and strategically important research underlying the development of new drug delivery vehicles. We propose to sample phase diagram of...

We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the...

The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent...

We propose to investigate the spin dynamics in the Ortho-II order YBCO6.5 superconductor at energies above 100 meV. This study will be aimed at searching for the broadening of...

Mixtures of methanol with water and ammonia dominate the chemistry of cometary bodies, leftovers of the building blocks of the outer planets. We have previously determined the...

BiFeO3 is the most widely studied multiferroic and rare earth doping overcomes problems associated with phase metastability and leakage which have hampered applications. We...
