Excitation caging in a vertex-frustrated quasiperiodic Einstein artificial spin ice
T. Wang, F. Museur, G. M. Macauley +5
Naturally occurring bulk quasicrystals are rare, and magnetic instances are rarer still, with chemical constraints typically permitting the synthesis of approximants rather than tr…
Magnetic-Field Control of Emergent Order in a 3D Dipolar Pyramid Artificial Spin Ice
Luca Berchialla, Gavin M. Macauley, Flavien Museur +2
We realize a three-dimensional artificial spin ice of disconnected nanomagnets interacting solely via dipolar coupling, patterned on square pyramids. This Pyramid artificial spin i…
Realizing Blume-Capel Degrees of Freedom with Toroidal Moments in a Ruby Artificial Spin Ice
Luca Berchialla, Gavin M. Macauley, Flavien Museur +4
Realizing exotic Hamiltonians beyond the Ising model is a key pursuit in experimental statistical physics. One such example is the Blume-Capel model, a three-state spin model, whos…
Ferromagnetic fragmented state in the pyrochlore HoRuO
F. Museur, J. Robert, F. Morineau +10
The consecutive magnetic ordering of the Ho and Ru ions in the pyrochlore Ho2Ru2O7 and their interplay are investigated by neutron scattering, magnetic and specific heat measuremen…
Collective magnetic state induced by charge disorder in the non-Kramers rare-earth pyrochlore TbScNbO
Y. Alexanian, E. Lhotel, R. Ballou +15
Geometrical frustration, as in pyrochlore lattices made of corner-sharing tetrahedra, precludes the onset of conventional magnetic ordering, enabling the stabilization of fluctuati…
Neutron scattering from fragmented frustrated magnets
F. Museur, E. Lhotel, P. C. W. Holdsworth
The fragmentation description is used to analyse calculated neutron scattering intensities from kagomé ice and spin ice systems. The longitudinal, transverse and harmonic fragments…
Coherent phonons and the interplay between charge density wave and Mott phases in 1-TaSe
C. J. Sayers, H. Hedayat, A. Ceraso +9
1-TaSe is host to coexisting strongly-correlated phases including charge density waves (CDWs) and an unusual Mott transition at low temperature. Here, we investigate coher…
