PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions. There are 3 potentially strong interactions, the first neighbor interaction couples the magnetic ions into...

Lu and Ho counterparts of RE3Fe5O12 will be an appropriate platform to reveal the complexmagnetic ground state of rare earth iron garnets with common formula RE3Fe5O12. Lu3+...

A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+)....

A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which...

Our previous INS experiments on the metal-organic ferrimagnetic compound CrCl2(pyz)2 revealed only a very weak dispersive mode below 1 meV. This energy scale is significantly...

Heusler alloys have gained important place in condensed matter physics due to their versatile functional properties such as large magnetoresistance, giant magnetocaloric effect,...

This experiment will use high resolution neutron diffraction to investigate the crystal and magnetic structure of the cobalt adipate framework, Co(CO2(CH2)4CO2), at lower...

Despite many previous attempts, Sr4Fe6O12 (the expected fully reduced composition for Sr4Fe6O13-x) has not been synthesised. It is of interest because it is believed to contain...

Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic...

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...

Elucidating the nature of magnetism in a high temperature superconductor is important. Our previous neutron measurements at low temperature revealed a resonance mode at Q = (pi,...

Back up experiment to fill gap in the schedule if beamtime is available

Our previous studies of the hole-doped antiferromagnet La1.75Sr0.25CoO4 have shown the distinctive "Hour-Glass" dispersion attributed to magnetic and charge ordered stripes....

Heisenberg antiferromagnetic (HAF) S = ½ chains are famous for their gapless magnetic excitation spectrum. Interestingly, in SrCuO2 and Sr2CuO3, which are some of the best...

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...

This proposal forms a very specific part of our project to investigate complex magnetic structures in rare earth intermetallics. In extensive bulk measurements on high purity...

We will use MAPS to measure the complete spin excitation spectrum of the quasi-two-dimensional S=3/2 antiferromagnet La2CoO4. The measurement is motivated by recent observations...

We are proposing to investigate the magnetic excitations of NdB4 in zero field using LET. NdB4 crystallises into tetragonal structure where the Nd ions forms layers which map to...

The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model uniquely provides exactly...
