Title: Behavior of the breathing pyrochlore lattice Ba₃Yb₂Zn₅O₁₁ in applied magnetic field

Abstract

The breathing pyrochlore lattice material Ba₃Yb₂Zn₅O₁₁ exists in the nearly decoupled limit, in contrast to most other well-studied breathing pyrochlore compounds. As a result, it constitutes a useful platform to benchmark theoretical calculations of exchange interactions in insulating Yb³⁺ magnets. Here we study Ba₃Yb₂Zn₅O₁₁ at low temperatures in applied magnetic fields as a further probe of the physics of this model system. Experimentally, we consider the behavior of polycrystalline samples of Ba₃Yb₂Zn₅O₁₁ with a combination of inelastic neutron scattering and heat capacity measurements down to 75 mK and up to fields of 10 T. Consistent with previous work, inelastic neutron scattering finds a level crossing near 3 T, but no significant dispersion of the spin excitations is detected up to the highest applied fields. Refinement of the theoretical model previously determined at zero field can reproduce much of the inelastic neutron scattering spectra and specific heat data. A notable exception is a low temperature peak in the specific heat at ~0.1 K. This may indicate the scale of interactions between tetrahedra or may reflect undetected disorder in Ba₃Yb₂Zn₅O₁₁.

We present time-of-flight inelastic neutron scattering measurements at low temperature on powder samples of the magnetic pyrochlore oxides Tb₂Ti₂O₇ and Tb₂Sn₂O₇. These two materials possess related, but different ground states, with Tb₂Sn₂O₇ displaying "soft" spin ice order below T_N approx 0.87 K, while Tb₂Ti₂O₇ enters a hybrid, glassy-spin ice state below T_g approx 0.2 K. Our neutron measurements, performed at T = 1.5 K and 30 K, probe the crystal field states associated with the J = 6 states of Tb³⁺ within the appropriate Fd3-barm pyrochlore environment. These crystal field states determine the size and anisotropy of the Tb³⁺ magneticmore »« less

Crystal Structure and Magnetic Properties of the Breathing Kagome Ising Antiferromagnet Yb₃Ni₁₁Ge_4.63

Journal Article Takahashi, Mitsuru ; Nawa, Kazuhiro ; Okuyama, Daisuke ; ... - Journal of the Physical Society of Japan

We have investigated magnetic properties of the rare-earth based intermetallic compound Yb₃Ni₁₁Ge_4.63 (YNG), where Yb³⁺ ions form a breathing-kagome lattice. Single-site 4f electron wavefunctions of the ground-state doublet are deduced from magnetization and heat capacity measurements. The Weiss temperatures are quite anisotropic as Θ^a = -0.01(2) K (H ∥ a) and Θ^c = -0.67(2) K (H ∥ c), indicating Ising-like spin–spin interactions dominating in this compound. Low-temperature neutron diffraction confirms absence of magnetic Bragg peaks down to 0.05 K, whereas enhancement of broad peaks below 0.8 K was observed, a signature of short-range spin correlations. Furthermore, competing interactions on themore »« less
