Modulation in Molecular Materials - Variable Temperature
Modulation occurs when there is ordering on two (or more) length scales. When the ratio of these is an integer, the modulation is said to be commensurate, i.e. one ordering is... -
Hydrogen Release Systems: MX2.(NH3)n (M=Mg, X=Cl) with LiH and MgH2
The applicants seek 3 days of beam time on POLARIS to study hydrogen release systems comprising M(NH3)6X2 (M=Mg, X=Cl) coupled with LiH and MgH. Mg(NH3)6Cl2 is an important... -
Superstructures in lithium cobaltate
The battery material LixCoO2 has recently been shown to have high thermopower comparable to NaxCoO2 at high x. In the case of NaxCoO2 we showed using neutron Laue diffraction on... -
Structural and magnetic orders in Ga-V oxide spinels
In certain materials, notably with the spinel structure, orbital ordering can result in the formation of a ground state with electrons delocalising between small numbers of...
