Absence of long-range order in a three-dimensional stacked Ising antiferromagnet on kagome lattice.

• We study a frustrated Ising antiferromagnet on a stacked kagome lattice (SIAKL). • We explore the possibility of any kind of long-range ordering at finite temperature. • Various quantities and their finite-size scaling are studied by Monte Carlo method. • Unlike other similar systems SIAKL remains disordered at any finite temperature. • SIAKL is a rare example of a 3D Ising paramagnet with unfrustrated stacking coupling. We study the possibility of long-range ordering (LRO) in a 3D system of vertically stacked layers of Ising antiferromagnet on a kagome lattice (SIAKL). Monte Carlo simulations are carried out for a varying interlayer coupling strength and a finite-size scaling analysis is performed for selected cases. Unlike in the related Ising system on a triangular lattice, in which even a finite number of the layers can stabilize LRO, or the Heisenberg system on the same kagome lattice, in which LRO emerged in 3D for a sufficient strength of the interlayer coupling, no LRO could be observed in the present model. This makes SIAKL a rare example of a 3D Ising paramagnet composed of frustrated layers coupled by unfrustrated interaction. [ABSTRACT FROM AUTHOR]
