Degenerate ground-states in Ho2-xYxSn2O7
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... -
Response of PAN-pyrene-micelle based sensors to metal ions
We have been studying the solution interactions leading to formation of solid polymer-surfactant films at the air-solution interface. We want to use the mesostructures in the... -
Bilayer modification and charge screening by simple ions
Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported DPPC bilayer films. At low concentrations... -
The effect of combined modifiers: understanding the interactions between alka...
The mixed alkali effect is a well-known phenomenon whereby combining two alkalis in a ternary glass system can produce physical properties which can be superior to, but cannot... -
Effect of calcium ions and ionic strength on model bilayer structure
Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported bilayer films. In this proposal we... -
Determining the magnetic moments of Co and Mn ions in the Ca3CoMnO6 unique mu...
Ca3Co1.05Mn0.95O6 is a rather unique multiferroic being the only known system with displaying collinear magnetic order that breaks inversion symmetry. To date it was not... -
High Temperature Spin Transition in LaCoO3
We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change... -
Structural study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
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)... -
Water librations in proton conducting hydrated alkali thio-hydroxogermanates
We propose to perform a systematic study of the intermolecular librational mode of molecular water in the proton conducting hydrated alkali thio-hydroxogermanates... -
