The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model in quantum magnetism . This is in part due to its intrinsic interest but also...

We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence...

We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition...

There is no systematic data in the literature about the transmission of neutron resonance filters. Such information probably exists in various instrument-log-books, but it would...

The frustration of triangular antiferromagnets with isotropic interactions leads to a variety of ground states even for classical spins. In regions where several classical...

Justification: There is no systematic data in the literature about the transmission of neutron resonance filters. Such information probably exists in various...

This proposal concerns SrCu2(BO3)2, a realization of the Shastry-Sutherland model, which is of particular interest in frustrated quantum magnetism. In this case, we are...

NiPS3 is a magnetic material. Its structure has similarities to graphite in that the atoms are strongly bound in planes but the planes are only weakly bound. It is called...

The closely related LiHoF4 and LiErF4 compounds have attracted a lot of interest as the dipolarnature of the coupling between spins allows for the study of quantum phase...

We propose to investigate the roles of the spin-orbit interaction and geometrical frustration in stabilising a quantum spin liquid phase (QSL) in some iridate systems. µSR is a...

We wish to study the magnon dynamics in FePS3, which appears to be a good approximation of a two-dimensional Ising magnet on a honeycomb lattice with spin 2. Numerous theory...

In majority of magnetic compounds interactions between spins, that reside on magnetic ions, result in a long-range ordered state below a critical temperature. In some materials...

The Heisenberg antiferromagnet is a well-known model used to describe the magnetic properties of layered and metal-organic Mott insulators which have been explored both...

LiErF4 is an example of an XY dipolar coupled antiferromagnet with planar anisotropy. As such it exhibits a quantum phase transition (QPT) in a small field of 4kOe, which is of...

Materials with antiferromagnetic interactions between spins on a triangle lattice inherently exhibit large frustration between similar energy ground states giving rise to novel...

Preliminary bulk measurements show that Ba(TiO)Cu4(PO4)4 is a potentially exciting candidate for studies of low-dimensional magnetism. However, currently relatively little is...

We propose to continue our investigation on LET of the Shastry-Sutherland compound SrCu2(BO3)2. The first part of the experiment aims to establish the Q-dependence, which will...

Erbium iron garnet is a technologically important material with potential use in quantum computing. The predicted presence of a magnetic resonance and an optically active erbium...

In a vast majority of materials that contain a magnetic ion the interaction between magnetic moments residing on magnetic ions causes them to order in a particular fashion. The...
