Small particles with dimensions of a few hundred nanometers tend to behave differently when confined in small spaces. Examples of such situations are easy to find in nature --...

We wish to measure the magnetic excitations and subgap states in a doped (x=0.06) spin ladder using MERLIN. The purpose of the measurements is to ascertain the relationship...

This proposal seeks to explore a multiferroic material new to science, that of the antiferroelectric ¿ antiferromagnetic ceramic Bi0.8Nd0.2FeO3. This new class of material is of...

The aim of the proposed experiment is to determine the temperature dependence of the ordered magnetic structures of LaMnSbO and NdMnSbO. These oxy-antimonides are related to the...

Perovskite oxides exhibit a large array of interesting electronic properties. Owing to their difficult synthesis (requiring extremely high pressures) the MOsO3 Osmates offer a...

Because of the potential applications of multiferroicity, the discovery of a new multiferroic (MF) material is invariably met with great enthusiasm in the condensed matter...

The Mn(II) phases LaSrMnO3.5 and LaBaMnO3.5 have been prepared by the topotactic reduction of LaSrMnO4 and LaBaMnO4 respectively. Preliminary neutron diffraction data show that...

We propose to use muon spin relaxation to examine the anomalous magnetic phase behaviour of Ba2MnMoO6. This compound shares the frustrated geometry that leads to a valence bond...

UPd3 exhibits four antiferroquadrupolar (AFQ) ordered phases below T0=7.6K. We have determined their order parameters using resonant x-ray diffraction. UPd3 has the dhcp crystal...
