Here, we report results on the magnetic and microwave properties of polycrystalline Y-type hexaferrite synthesized by sol-gel auto-combustion and acting as a filler in a composite microwave-absorbing material. The reflection losses in the 1–20 GHz

We show that the structure of multifilament MgB2 wires made by the powder-in-tube (PIT) method can be texturized by annealing the structure under high isostatic pressure. Our results show that we obtained continuous fibers with a uniform diameter of

The data presented has to do with identifying the various phases arising during the synthesis of the Y-type hexaferrite series Ba0.5Sr1.5Zn2-xNixFe12O22 by auto-combustion that we deem important for their microstructural and magnetic properties. The

We report transport, electromechanical, and structural properties of single core MgB2/Fe wire produced using a new fabrication method, called designed internal Mg diffusion (IMD) process, which relies on the use of non-stoichiometric Mg + B pellets w

We consider the influence of the magnetic cation (Ni2+) substitution on the structural and magnetic properties of Ba0.5Sr1.5Zn2-xNixFe12O22 (x = 0.8, 1, 1.5) powders. The powders were synthesized by using the citric-acid sol–gel auto-combustion met

We present results from a study on the influence of the preparation technique on the structural and magnetic properties of Ba 0.5 Sr 1.5 Zn 2 Fe 12 O 22 powders synthesized by citric-acid sol-gel auto-combustion and sonochemistry and characterized by
