The perovskite-like family of ammonium formate frameworks AB(HCO2)3, where A is a divalent metal ion and B is an (alkyl)ammonium or guanadinium, is of great interest for its...

Exchange bias (EB) effect, characterized by a shift of the hysteresis loop along the magnetic field axis, has attracted considerable attention because of its significance in...

Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect (MVE) in...

Ni-Mn based Heusler alloys are magnetic multifunctional materials currently under intense research efforts thanks to their unique coexistence of a reversible structural...

Hexaferrites are well known for their applications as permanent magnet and memory devices. In recent years, the interest in hexaferrite has grown from the point of view of...

The NH4M(formate)3 (M = Mn, Fe, Co and Ni) series are the most promising members of a new family of multiferroics in which ferroelectric ordering is driven by hydrogen-bonding...

The spin Jahn-Teller effect stabilises 3D magnetic order in an otherwise frustrated system via magnetoelastic coupling, spontaneously at the magnetic phase transition. Examples...

Test of the NIMS low temperature pressure cell on WISH.

Multiferroics - where ferroelectric and magnetic orders co-exist - continue to be of technological and scientific importance, and of particular interest are the improper...

The National Physical Laboratory (NPL) and the WISH instrument team has worked together to enable simultaneous real-time high resolution (powder and single crystal) neutron...

Ga2-xFexO3 (GFO) is a ferrimagnetic magnetoelectric material presenting a Curie temperature above room temperature for x>1.3. It is therefore an interesting candidate for the...

Our recent study of CaFe3O5 revealed a remarkable discovery of electronic phase separation, similar to examples widely reported in manganite perovskites. Electronic phase...

The experiment will study the magnetic structure in the complex boride Mn3Co20B6. Substitutions in this compound makes it possible to tune the magnetic properties, thus, making...

We propose to use WISH to examine whether a transition between different spiral antiferromagnetic structures in zero magnetic field is the key to tricriticality at finite fields...

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has...

The Heusler alloys Ni-Mn-Ga are widely considered as a new generation of multifunctional smart materials due to the mutual interplay between structural and magnetic properties...

Exotic electronic states are of great interest to fundamental science, such as the quantum spin-liquids (QSLs) which were theorised to behave like a sea of resonating spin...

Metastable multiferroic perovskites of the BiFe1-xScxO3 system, stabilised by high-pressure and high-temperature synthesis, demonstrate irreversible phase transformations upon...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...
