Tensor component distinction of magnetic non-ferroelastic domain pairs

Abstract

Global tensor distinction considers whether or not a physical property tensor can distinguish among all domains that arise in a phase transition. Domain pair tensor distinction considers whether or not a property tensor can distinguish between a pair of domains. To determine how switching of a pair of domains may be accomplished requires in addition tensor component distinction, i.e. the determination of which components of a property tensor distinguish the two domains. These tensor component distinctions are necessary but not sufficient conditions for switching. Here, we consider all magnetic non-ferroelastic domain pairs and determine the tensor component distinction for each for a wide variety of physical property tensors.
