Magnetization beyond the Ising limit of HoTiO
L. Opherden, T. Herrmannsdörfer, M. Uhlarz +8
We report that the local Ising anisotropy in pyrochlore oxides - the crucial requirement for realizing the spin-ice state - can be broken by means of high magnetic fields. For the…
Magnetic interactions and spin dynamics in the bond-disordered pyrochlore fluoride NaCaCoF
J. Zeisner, S. A. Bräuninger, L. Opherden +9
We report high-frequency/high-field electron spin resonance (ESR) and high-field magnetization studies on single crystals of the bond-disordered pyrochlore NaCaCoF. Frequen…
Tuning interactions in the spin-ice materials DyGeSiO by silicon substitution
T. Stöter, M. Antlauf, L. Opherden +10
We report that the lattice constant of DyGeSiO () can be systematically reduced by substituting the non-magnetic germanium ion in the cu…
Evidence for a dynamical ground state in a frustrated pyrohafnate Tb2Hf2O7
V. K. Anand, L. Opherden, J. Xu +9
We report the physical properties of Tb2Hf2O7 based on ac magnetic susceptibility χ_ac(T), dc magnetic susceptibility χ(T), isothermal magnetization M(H), and heat capacity C_p(T)…
Quasiparticle Excitations in the Superconducting State of FeSe Probed by Thermal Hall Conductivity in the Vicinity of the BCS-BEC Crossover
Tatsuya Watashige, Stevan Arsenijević, Takuya Yamashita +10
There is growing evidence that the superconducting semimetal FeSe ( K) is in the crossover regime between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-couplin…
