Abstract

The data presented has to do with identifying the various phases arising during the synthesis of the Y-type hexaferrite series Ba_0.5Sr_1.5Zn_2-xNi_xFe₁₂O₂₂ by auto-combustion that we deem important for their microstructural and magnetic properties. The data and the related analyses support the research paper "Ni-substitution effect on the properties of Ba_0.5Sr_1.5Zn_2-xNi_xFe₁₂O₂₂ powders" [1]. Thus, the parameters are presented of the phases appearing after auto-combustion and after the initial annealing at 800 °C, namely, crystal cell and crystallite size. Also, additional data are provided obtained by EDS concerning the Ba:Sr:Zn:Ni:Fe ratio in Ba_0.5Sr_1.5Zn_2-xNi_xFe₁₂O₂₂ (x = 0.8, 1, 1.5) samples synthesized at 1170 °C for 10 h. The data can be used as a reference in establishing how the phases distinguished during the initial process of auto-combustion affect the Ba_0.5Sr_1.5Zn_2-xNi_xFe₁₂O₂₂ powders, which are candidates for room-temperature multiferroic materials. The data have not been published previously and are made available to permit critical or further analyses.
