Magnetic Excitations in YbNiSn
YbNiSn is an Ising ferromagnet with non-colinear spins that undergoes a first order magnetic transition in low magnetic field (0.9 T). The transition is associated with strong... -
The full spin-wave dispersion of CaFe2O4 in the A and B phases:
CaFe2O4 shows an interplay between magnetic structures termed the A and B phases. In this proposal, we request time to measure the spin wave dispersion using MERLIN. Previous... -
Study of possible quantum chains in Nd2Zr2O7 in high [110] fields
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... -
Spin excitations in the first magnetic Weyl semimetal Co3Sn2S2
In contrast to the extensively verified Weyl semimetals with broken inversion symmetry, magnetic Weyl semimetals, which break time reversal symmetry, were only theoretically... -
Lattice dynamics in the giant barocaloric Ammonium Sulfate
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,... -
Nematic spin fluctuations in tetragonal La2-xSrxCuO4
Uniaxial stress has been used to study the Fe-based superconductors with spectacular results. Both the transport properties and the low-energy magnetic excitations have been... -
Investigation of a new three-dimensional frustrated quantum magnet
Interesting behaviour in Heisenberg spin systems originates from networks of triangles or tetrahedra, where spins interact via antiferromagnetic interactions. In 3D there are... -
Determination of the Spinon Confining Potential in a 1D, Spin-1/2 XXZ Antifer...
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... -
Excitation spectrum of the frustrated spinel GeCo2O4
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... -
Spin dynamics in the extended Kagome system YBaCo4O(7+x)
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...
