Ni 2 Mo 3 O 8 : Complex Antiferromagnetic Order on a Honeycomb Lattice

January 18, 2019
Author(s)
Jennifer R. Morey, Allen Scheie, John P. Sheckelton, Craig Brown, Tyrel M. McQueen
Theoretical studies have predicted the existence of topological magnons in honeycomb compounds with zig-zag antiferromagnetic (AFM) order. Here we report this discovery of zig-zag AFM order in the layered and non-centrosymmetric honeycomb nickelate Ni 2Mo

Constructive Relationships Between Algebraic Thickness and Normality

August 4, 2015
Author(s)
Joan Boyar, Magnus G. Find
We study the relationship between two measures of Boolean functions; "algebraic thickness" and "normality". For a function f, the algebraic thickness is a variant of the "sparsity", the number of nonzero coefficients in the unique F_2 polynomial
