Quasispins of vacancy defects in Ising chains with nearest- and next-to-nearest-neighbour interactions
Shijun Sun, Arthur P. Ramirez, Sergey Syzranov
Motivated by frustrated magnets and quasi-one-dimensional magnetic materials, we study the magnetic properties of 1D Ising chains with nearest-neighbour (NN) and weaker next-to-nea…
A van der Waals antiferromagnetic topological insulator with weak interlayer magnetic coupling
Chaowei Hu, Xiaoqing Zhou, Pengfei Liu +11
Magnetic topological insulators (TI) provide an important material platform to explore quantum phenomena such as quantized anomalous Hall (QAH) effect and Majorana modes, etc. Thei…
Magnetically tunable dielectric materials
G. Lawes, T. Kimura, C. M. Varma +3
The coupling between localized spins and phonons can lead to shifts in the dielectric constant of insulating materials at magnetic ordering transitions. Studies on isostructural Se…
Large Low Temperature Specific Heat in Pyrochlore BiTiO
Brent C. Melot, Ronald Tackett, Jim O'Brien +4
Both amorphous and crystalline materials frequently exhibit low temperature specific heats in excess of what is predicted using the Debye model. The signature of this excess specif…
Magnetic phase evolution in the spinel compounds ZnCoCrO
Brent C. Melot, Jennifer E. Drewes, Ram Seshadri +1
We present the magnetic properties of complete solid solutions of ZnCrO and CoCrO: two well-studied oxide spinels with very different magnetic ground states. ZnCr$_…
Soft Manifold Dynamics Behind Negative Thermal Expansion
Z. Schlesinger, J. A. Rosen, J. N. Hancock +1
Minimal models are developed to examine the origin of large negative thermal expansion (NTE) in under-constrained systems. The dynamics of these models reveals how underconstraint…
