YbNiSn is a Yb analogue of ferromagnetic superconductors URhGe and UCoGe. All materials share the same crystal structure, have similar Curie temperatures and a similar...

We have recently discovered solitary magnons in the classical magnet CaFe2O4 below 3 meV. in this experiment we propose to extend this to higher energy transfers to track how...

In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric...

Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an...

Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different...

The spinel GeCo2O4 is a promising compound to establish the consequences of geometrical frustration, as the magnetic Co2+ ions are on a network of corner-sharing tetrahedra...

SrCo2V2O8 is a quasi-1D, S-1/2 antiferromagnet with XXZ anisotropy. Weak interchains coupling result in long-range magnetic order at a finite temperature TN. A spinon continuum...

The organic-inorganic perovskites with chemical formula CH3NH3PbB(Br,Cl,I)3 have been implicated as being efficient photovoltaic materials. Theoretical calculations and...

The proposal requests time to measure the low-energy excitations in CaFe2O4 as a function of temperature. Previous experiments have observed a series of in-gap states at high...

Recent high resolution spectroscopy has found countable and discrete excitations in the two dimensional magnet CaFe2O4. This work aims to track these excitations to higher...

The proposal requests time on OSIRIS to measure the low-energy magnetic fluctuations in CeRhSi3. This compound is a noncentrosymmetric superconductor under pressures of ~10...

The pyrochlores provide an excellent model system for studying the interaction of framework vibrational modes, defects and magnetism. We propose to investigate these couplings...

HoFeO3 have two magnetic ions, Ho3+ and Fe3+, and three types of magnetic interactions between these two ions. These three interactions play different roles at different...

Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted....

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...

Nd2Zr2O7 is a new candidate prominent to quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field...

Geometrically frustrated spin systems have been studied extensively for decades because of many intriguing phenomena, exemplified by the non-magnetic quantum disordered states....
