Molecular-field-theory fits to magnetic susceptibilities of antiferromagnetic GdCu₂Si₂, CuO, LiCrO₂, and α-CaCr₂O₄ single crystals below their Néel temperatures

Journal Article Johnston, David C. - Journal of Magnetism and Magnetic Materials

A recently-developed molecular field theory (MFT) has been used to fit single-crystal magnetic susceptibility χ versus temperature T data below the respective antiferromagnetic ordering temperature T_N for a variety of collinear and coplanar noncollinear Heisenberg antiferromagnets. The spins in the system are assumed to interact by Heisenberg exchange and to be identical and crystallographically equivalent. The fitting parameters for χ(T ) of collinear antiferromagnets are measurable quantities: the Weiss temperature θ_p in the Curie-Weiss law, TN, χ(T_N), and the spin S. For coplanar noncollinear helix and cycloid structures, an additional fitting parameter is the turn angle between layers of ferromagnetically-alignedmore »« less

Magnetic soft modes in the distorted triangular antiferromagnet -CaCr2O4

Journal Article Toth, Sandor ; Lake, Bella ; Hradil, Klaudia ; ... - Physical Review Letters

-CaCr2O4 is a spin-3/2, distorted triangular lattice antiferromagnet with a simple 120 spin structure that masks the complex pattern of exchange interactions. The magnetic excitation spectrum has been measured using inelastic neutron scattering on powder and single crystal samples. It reveals unusual low energy modes which can be explained by linear spin-wave theory assuming nearest and next-nearest neighbor interactions. The mode softening is due to the next-nearest neighbor interactions and indicates a new magnetic phase nearby as revealed by the phase diagram constructed for this system. The extracted direct exchange interactions correlate well with the Cr3+{Cr3+ distances and are inmore »« less
Evolution of magnetic field induced ordering in the layered quantum Heisenberg triangular-lattice antiferromagnet Ba₃CoSb₂O₉

Journal Article Fortune, N. A. ; Huang, Q. ; Hong, T. ; ... - Physical Review B

Quantum fluctuations in the effective spin-12 layered triangular-lattice quantum Heisenberg antiferromagnet Ba₃CoSb₂O₉ lift the classical degeneracy of the antiferromagnetic ground state in magnetic field, producing a series of novel spin structures for magnetic fields applied within the crystallographic ab plane, including a celebrated collinear “up-up-down” spin ordering with magnetization equal to 1/3 of the saturation magnetization over an extended field range. Theoretically unresolved, however, are the effects of interlayer antiferromagnetic coupling and transverse magnetic fields on the ground states of this system. Additional magnetic field induced phase transitions are theoretically expected and in some cases have been experimentally observed, butmore »« less

Magnetic excitations in the spin-1/2 triangular-lattice antiferromagnet Cs₂CuBr₄

Journal Article Zvyagin, S. A. ; Ozerov, M. ; Kamenskyi, D. ; ... - New Journal of Physics

We present on high- field electron spin resonance (ESR) studies of magnetic excitations in the spin- 1/2 triangular-lattice antiferromagnet Cs₂CuBr₄. Frequency- field diagrams of ESR excitations are measured for different orientations of magnetic fields up to 25 T. We show that the substantial zero- field energy gap, Δ ≈ 9.5 K, observed in the low-temperature excitation spectrum of Cs₂CuBr₄ [Zvyagin et al:, Phys. Rev. Lett. 112, 077206 (2014)], is present well above T_N. Noticeably, the transition into the long-range magnetically ordered phase does not significantly affect the size of the gap, suggesting that even below T_N the high-energy spin dynamicsmore »« less
