Autor: D. R. Yahne, B. Placke, R. Schäfer, O. Benton, R. Moessner, M. Powell, J. W. Kolis, C. M. Pasco, A. F. May, M. D. Frontzek, E. M. Smith, B. D. Gaulin, S. Calder, K. A. Ross
Publikováno v: Physical Review X, Vol 14, Iss 1, p 011005 (2024)
The dipolar-octupolar (DO) pyrochlores, R_{2}M_{2}O_{7} (R=Ce,Sm,Nd), are key players in the search for realizable novel quantum spin liquid (QSL) states as a large parameter space within the DO pyrochlore phase diagram is theorized to host QSL state

The Ce^{3+} pseudospin-1/2 degrees of freedom in the pyrochlore magnet Ce_{2}Zr_{2}O_{7} are known to possess dipole-octupole character, making it a candidate for novel quantum spin liquid ground states at low temperatures. We report new polarized ne

Ground state selection under pressure in the quantum pyrochlore magnet Yb2Ti2O7
Autor: E. Kermarrec, J. Gaudet, K. Fritsch, R. Khasanov, Z. Guguchia, C. Ritter, K. A. Ross, H. A. Dabkowska, B. D. Gaulin
Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-5 (2017)
An understanding of how quantum spin liquids arise in frustrated magnets at low temperatures remains elusive. Here the authors demonstrate a pressure-driven ferromagnetic transition out of a quantum spin liquid phase in the pyrochlore Yb2Ti2O7, highl

Crystallization of spin superlattices with pressure and field in the layered magnet SrCu2(BO3)2
Autor: S. Haravifard, D. Graf, A. E. Feiguin, C. D. Batista, J. C. Lang, D. M. Silevitch, G. Srajer, B. D. Gaulin, H. A. Dabkowska, T. F. Rosenbaum
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-6 (2016)
Spin 1/2 dimer systems in an external magnetic field behave as a lattice gas of hard-core bosons, and can undergo condensation. Here the authors show in SrCu2(BO3)2that new fractionally crystallized states are not only possible, but also tuneable wit

Spin-orbital order and excitons in magnetoresistive HoBi
Autor: J. Gaudet, H.-Y. Yang, E. M. Smith, T. Halloran, J. P. Clancy, J. A. Rodriguez-Rivera, Guangyong Xu, Y. Zhao, W. C. Chen, G. Sala, A. A. Aczel, B. D. Gaulin, F. Tafti, C. Broholm
Publikováno v: Physical Review B. 107
The magnetism of the rock-salt $fcc$ rare-earth monopnictide HoBi, a candidate topological material with extreme magnetoresistance, is investigated. From the Ho$^{3+}$ non-Kramers $J$=8 spin-orbital multiplet, the cubic crystal electric field yields

Autor: D D, Maharaj, G, Sala, M B, Stone, E, Kermarrec, C, Ritter, F, Fauth, C A, Marjerrison, J E, Greedan, A, Paramekanti, B D, Gaulin
Publikováno v: Physical review letters. 124(8)
We report time-of-flight neutron spectroscopy and neutron and x-ray diffraction studies of the 5d^{2} double perovskite magnets, Ba_{2}MOsO_{6} (M=Zn,Mg,Ca). These materials host antiferromagnetically coupled 5d^{2} Os^{6+} ions decorating a face-cen

Publikováno v: Physical review letters. 119(18)
We report neutron scattering measurements on Er_{2}Pt_{2}O_{7}, a new addition to the XY family of frustrated pyrochlore magnets. Symmetry analysis of our elastic scattering data shows that Er_{2}Pt_{2}O_{7} orders into the k=0, Γ_{7} magnetic struc
