Property Tensors and Ferrotoroidic Domains

Abstract

Primary and secondary property tensors of ferrotoroidic domains are derived. It is shown how these properties may be applied in determining possible switching of domains by analyzing the expansion of the difference in free enthalpy between domains and concomitantly determining which of these properties distinguish between domains.

Keywords:

• Ferrotoroidic domains
• property tensors
