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

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

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...

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...

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....

Given the challenges in providing efficient and non-harmful refrigeration, it is timely to study barocaloric systems, which offer cooling power via the application of pressure,...

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...

Recently, new type of frustrated magnets, BaV10O15 and SrV10O15, were found to exhibit interesting phenomena due to mixed valence ions forming a modified triangular lattice....

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 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...

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

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 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...

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...

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...

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...

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...

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...
