Abstract

In this paper, the magnetic properties of an exchange-coupled hard-soft bilayer system have been analyzed based on its energy-barrier characteristics. Analytical solutions of the magnetic and structural parameters such as the energy barriers, the coercivities, the critical coupling-constant, the critical coupling dimension of soft phase, and the energy product have been derived. These analytical solutions reveal the correlation between the magnetic properties and the physical dimensions of its soft and hard phase constituents.
