Ultralow-Field Triplon Condensation in a Spin-Ladder Magnet
Ankit Labh, Ross H. Colman, Jakub Šebesta +12
We realise the first ultralow-field Bose-Einstein condensation of triplons in a spin-ladder magnet, uncovering a quantum critical point at only T in Henmilite ($\…
Demagnetization effect on magnetic noise measurements in spin ice materials
F. Morineau, C. Paulsen, G. Balakrishnan +4
Magnetic noise spectroscopy provides direct access to spontaneous time-dependent magnetization fluctuations in correlated magnetic systems, including spin liquids, spin ices, and s…
Complex magnetic interactions in geometrically frustrated TbOF
Pim Witte, Denis Sheptyakov, Elsa Lhotel +5
We have identified TbOF as a unique frustrated and mixed-anion lattice, hosting unconventional magnetism. By means of magnetization, specific heat and neutron diffraction measureme…
Melting upon cooling in a quantum magnet
K. JaksetiÄ, T. Arh, M. Pregelj +19
Heating enhances thermal fluctuations and typically leads to melting of solids, but in exceptional cases, heating can also cause liquids to solidify. The paradigm of this counterin…
About the origin of the magnetic ground state of TbIrO
Y. Alexanian, E. Lhotel, J. Robert +10
Magnetic-rare-earth pyrochlore iridates exhibit a rich variety of unconventional phases, driven by the complex interactions within and between the rare-earth and the iridium sublat…
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…
