Two‐Mode Stochastic Magnetic Structure in Nanocrystalline Soft Magnetic Fe–Zr Films

The magnetic structure of Fe(100-x)Zr(x) films (x = 0, 0.6, 1.8, 2.9, and 4.1 +/- 0.1 at%), which is characterized by the existence of stochastic domains determined by correlation magnetometry method, is discussed in terms of the random anisotropy model. It is found that two modes of the magnetic anisotropy field of stochastic domains are formed, which differ in the exchange stiffness magnitude and determine the existence of two modes of the coercive field found in the magnetic hysteresis loops.
