Fully unconstrained non-collinear magnetism in triangular Cr and Mn monolayers and overlayers on Cu(111) substrates
(2000) In Journal of Physics: Condensed Matter 12. p.7025-7025- Abstract
- A recently developed fully unconstrained approach to non-collinear magnetism has been applied to the investigation of the magnetic ground state of triangular free-standing Cr and Mn monolayers and overlayers on Cu(111) substrates. Such systems represent a physical realization of a frustrated two-dimensional antiferromagnet. We find that the ground state of the Cr monolayers is non-collinear; it shows (3)1/2×(3)1/2 periodicity with ±120° angles between the directions of the magnetic moments on neighbouring sites. Mn monolayers on the other hand have a collinear ground state with antiferromagnetically coupled rows and c(2×2) periodicity. The fully unconstrained description allows for a detailed investigation of the spin densities in the... (More)
