Internal stresses in superconducting bulk magnets studied by in situ neutron ...
Bulk high temperature superconductors are useful for permanent magnet applications because they can generate much stronger magnetic fields than ferromagnets and are more compact... -
A study of the metastable phase in Ca3Co2O6
Ca3Co2O6 is an unusual system, with a highly anisotropic magnetic behaviour and a series of regularly spaced steps in magnetisation appearing at low temperatures in a magnetic... -
Colossal Magnetoresistance in PrBa2Cu3O7-d
Large negative bulk magnetoresistance has recently been observed in ruthenocuprate materials RuSr2R2-xCexCu2O10-d (up to -47 % at 5 K in a 9 T field). This material exhibits -MR... -
Squeezing the frustration out of a kagome antiferromagnet ¿ a high pressure s...
Hertbertsmithite ZnCu3(OH)6Cl2 is a model S =1/2 kagome antiferromagnet, received much attention last years. From recent studies a sign of a nearby quantum phase transition... -
Studying the helimagnetic order and precursor phenomena in MnSi under pressure
The archetype chiral system MnSi belongs to the family of non-centrosymmetric cubic helimagnets where a helimagnetic ordering exists below the critical temperature of 29 K. This... -

The proposal develops recent observations on spin-lattice coupling in incommensurate materials (objective - measure influence of applied field on evolution of structural... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -
magnetic structure and step-like magnetization in Ca3Co2O6: a neutron diffrac...
Pure Ca3Co2O6 is a model system of ferromagnetic Ising chains arranged antiferromagnetically on a triangular net. Furthermore this system has aroused great interest because at... -
In-situ hydrogen decomposition studies of ammonia borane and the diammoniate ...
Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3...
