Magnetism in a family of square lattice antiferromagnets Ni(pyz) ( Cl, Br, I, NCS; pyz = pyrazine)
J. Liu, P. A. Goddard, J. Singleton +23
The crystal structures of Ni(pyz) ( = Cl (\textbf{1}), Br (\textbf{2}), I (\textbf{3}) and NCS (\textbf{4})) were determined at 298~K by synchrotron X-ray powder diffra…
Strange correlations in spin-1 Heisenberg antiferromagnets
Keola Wierschem, Pinaki Sengupta
We study the behavior of the recently proposed "strange correlator" [Phys. Rev. Lett. {\bf 112}, 247202 (2014)] in spin-1 Heisenberg antiferromagnetic chains with uniaxial single-i…
Magnetic phases in the S=1 Shastry-Sutherland model with uniaxial anisotropy
Lei Su, Keola Wierschem, Pinaki Sengupta
We explore the field induced magnetic phases of an model with single-ion anisotropy and large Ising-like anisotropy on a Shastry Sutherland lattice over a wide range of…
Quenching the Haldane gap in spin-1 Heisenberg antiferromagnets
Keola Wierschem, Pinaki Sengupta
We consider a quasi-one-dimensional system of spin-1 Heisenberg antiferromagnetic chains in 2D and 3D hypercubic lattices with interchain coupling and uniaxial single-ion aniso…
