Mechanisms of Magnetic Hysteresis in Heterogeneous Gd‒Zr‒Co‒Cu‒Fe Alloys
摘要
Abstract
The authors study the behavior of samples of (Gd,Zr)(CoCuFe)z alloy in magnetic fields oriented at different angles to their easy magnetization axes. The angular dependences of magnetization and coercivity are built. The hysteresis loops for the two main structural components of the samples are plotted using images of domain structure in demagnetizing fields. Results are analyzed by assuming there is a mixed mechanism of hysteresis in this family of alloys.
