We recently synthesised a new layered manganes oxide with a frustrated connectivity of Mn4+ ions. Variable temperature studies demonstrated a deviation from linearity at...

Bismuth ferrite, BiFeO3, is a much-studied ceramic showing both dielectric and magnetic ordering at relatively high temperatures. In order to improve its properties there has...

Multiferroic systems have more than one functionality, i.e. ferromagnetism, ferroelectricity, ferroelasticity and ferrotoroidicity. In nature there are few materials that...

Materials which exhibit triangular and Kagome lattices have attract much interest within the literature due to the potential of these materials to exhibit strong geometric...

Multiferroics and in particular BiFeO3 have recieved alot of interest. The potential of multiferroic materials to be incorporated into many devices such as sensors and memory...

We wish to probe the suggested existence of a high-temperature cubic perovskite phase in the multiferroic material BiFe0.7Mn0.3O3. The parent phase of this material, BiFeO3, was...

Antiferroelectric materials are attracting extensive attention due to their potential in energy storage applications. These materials exhibit a double polarisation-field...

Layered strontium ruthenate materials are a prime example of how closely competing energy scales found in strongly correlated electron systems can give rise to a broad range of...

Bismuth ferrite, BiFeO3, is a much-studied ceramic showing both dielectric and magnetic ordering at relatively high temperatures. In order to improve its properties there has...

We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found...
