Paper Title:
Research on Magnetic Properties of Nd2Fe14B/α-Fe/Nd2Fe14B Exchange-Coupled Trilayer Films
  Abstract

The magnetic hysteresis loops of Nd2Fe14B/α-Fe/Nd2Fe14B exchange-coupling trilayer film are simulated by micromagnetic theory, and the relationship between remanence, coercivity, energy products and soft magnetic thickness are discussed in detail. The results show that the hysteresis loops is rectangle and the trilayer films are in complete exchange-coupling region when the soft magnetic thickness is below the critical point(5nm); With the increase of the soft magnetic thickness, the coercivity of the trilayer films decreases monotonically. Maximum energy products are obtained when the soft magnetic thickness is 5nm.
