Recently we did muon spin relaxation (µSR) and inelastic neutron scattering (INS) measurements on the newly discovered tertragonal Ce-based ferromagnet CeRu2M2B (M = Al and Ga)...

Multiferroic materials which exhibit both magnetic and electric ordering offer the potential application in data storage, spintronics, and microelectronics. To date the most...

Our aim is to study with high resolution neutron powder diffraction the two orthorhombic phases of Mn2TeO6 at RT, so as to understand the origin of the observed structural...

We have identified new multi-anion solids with transition metals in unusual coordination environments and with apparently complex magnetic ordering. This experiment proposed for...

YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down...

The multiferroic perovskite BiFeO3 is the only material that displays both ferroelectric and antiferromagnetic order at RT. Significant efforts are aimed at better understanding...

This is a proposal to determine the magnetic structures of the Rb/NH3 and K/NH3 intercalates of FeSe. These compounds exhibit superconductivity when freshly prepared, but...

The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have...

Zeolites are porous crystals that make it possible to generate regularly arrayed alkali-metal nanoclusters. Potassium clusters arrayed in zeolite A show ferromagnetism below 7 K...

Oxides of 5d elements such as Ir and Os have been attracting much attention as candidates to realize novel types of electronic ground states stabilized by the strong spin orbit...

Our muSR study on Ce(Os1-xFex)2Al10 with x=0.4, which reveals long range magnetic ordering below 24K from the heat capacity, shows unexpected temperature dependence. The muSR...

Test of the NIMS low temperature pressure cell on WISH.

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...

In recent years there has been a large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

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...

A recent addition to the list of emergent materials is the ReBaCo4O7+delta family of compounds. Indeed, due to the magnitude of their oxygen uptake and release capability, they...

In this proposal, we would like to propose to perform neutron diffraction experiments on the powder samples of the frustrated antiferromagnets AFeO2 (A=Cu and Ag) using WISH. In...

Magnetic and orbital ordering in the manganese based perovskites has been of huge interest in solid-state physics since the 1950's. More recently, the family of AA′3Mn4O12...

In the coming year, we plan to build upon the success of last cycle by carrying out more hydrocarbon studies of this porous material NOTT-300 and one of its iso-structural...
