In this paper, we investigate the magnetic, dielectric, and impedance properties of Ba_2 − ySr_yZn₂Fe₁₂O₂₂ (y = 0.0–1.5) hexaferrite prepared by solid-state reaction process. The magnetic hysteresis loop suggested that the prepared hexaferrite exhibits room temperature hard ferromagnetic activity. The saturation magnetization (M_s), remanence (M_r), and magneton number (n_B) values are decreased with Sr²⁺ substitutional dopant at the Ba²⁺ site. On the other hand, Sr²⁺ doping enhances the β, H_a, and K_e values. The squareness ratio (M_r/M_s) is calculated to be 0.50, indicating the uniaxial anisotropy of BSZFO (y = 0.0–1.5) hexaferrite. Dielectric constant and dielectric loss values increased from 147 to 290 and 0.058 to 0.94, increasing Sr²⁺substitution from 0.0 to 1.5 at 1 MHz. This study has supported the rise in AC conductivity and decreases DC conductivity with the Sr²⁺ substitution.

在本文中，我们研究了 通过固态反应过程制备的Ba _{2-  y} Sr _y Zn ₂ Fe ₁₂ O ₂₂（y = 0.0-1.5）六方铁氧体的磁，介电和阻抗特性。磁滞回线表明所制备的六价铁氧体表现出室温的硬铁磁活性。Ba ²⁺位置的Sr ²⁺替代掺杂剂会降低饱和磁化强度（M _s），剩磁（M _r）和磁子数（n _B）值。另一方面，Sr ²⁺掺杂会增强β，H _a和K _e值。计算出的矩形比（M _r / M _s）为0.50，表明BSZFO（y  = 0.0-1.5）六方铁氧体的单轴各向异性。介电常数和介电损耗值从147增加到290，从0.058增加到0.94，在1 MHz时Sr ²⁺取代从0.0增加到1.5。这项研究支持了交流电导率的提高和用Sr ²⁺取代降低了直流电导率。
