Abstract
Thermal relaxation is studied in an array of interacting single domain uniaxial particles deposited on a planar hexagonal lattice. Coherent rotation of magnetization and perfect alignment of easy axes with applied field are assumed. The lattice is stretched in the direction of the easy axes and the coercivity and switching field distribution (SFD) are studied as functions of the stretching factor. Coercivity is found to have monotonic dependence on the stretching factor while the SFD function exhibits complicated behavior associated with a transition between configurations dominated by ferromagnetic and antiferromagnetic ordering.
