“…For a good absorber, when the microwave is incident on the surface of an absorber, the direct reflection of microwaves should be minimum to ensure as much as microwave propagating into the absorber. This requires the input impedance Z in equals free-space wave impedance Z 0 (377 Ω), which means the imaginary part of input impedance, ″ Z in approaches zero ohm while the corresponding real part of input impedance, ′ Z in approaches 377 Ω [36].

“…Due to their elasticity and easy processability, they are suitable for applications in which good elasticity and high fl exibility are required. These attributes in combination with unique magnetic characteristics rank them among progressive developing materials which have already found the utilization in microwave and radar technology, vibration absorbers, motor parts, memory devices, variable impedance surfaces, inductor cores, sensors of magnetic and electromagnetic fi elds and in many other technological applications (Vinayasree at al., 2016;Tong at al., 2013;Das at al., 2015). In this work, rubber magnetic composites were prepared by the incorporation of strontium ferrite into NR based pure rubber matrix or carbon black batch.…”

Two types of composites based on natural rubber (NR) and strontium ferrite were tested in this study. Composites of the first type were prepared by incorporation of strontium ferrite in the concentration range ranging from 0 to 100 phr (parts per hundred rubber) into pure NR based rubber matrix, while with those of the second type, strontium ferrite was dosed in the same concentration level into NR based rubber batch with constant amount of carbon black — 25 phr. For rubber matrices cross-linking, a standard sulfur based curing system was used. This work is focused on the effect of magnetic filler content on physico-mechanical, magnetic and thermo-physical properties of composite materials. Subsequently, the cross-link density and the structure of the formed sulfidic cross-links were examined. The results showed that the cross-link density of both types of composites increased with the increasing content of magnetic filler, while the structure of the sulfidic cross-links was almost not influenced by the amount of strontium ferrite. Tensile strength of rubber composites with pure rubber matrix was slightly improved by the incorporation of ferrite, while in case of composites based on a carbon black batch, the incorporation of magnetic filler resulted in the decrease of this characteristic. The presence of magnetic filler in both types of composites leads to a significant increase of the remanent magnetic induction.

“…Entretanto, devido à atração magnética, as nanopartículas de ferrita tendem a formar aglomerados que podem comprometer seu desempenho em certas aplicações. Uma das soluções propostas tem sido dispersar as nanopartículas em materiais não magnéticos [1][2][3][4][5][6][7][8][9][10]. Um material não magnético conveniente é a parafina, um material relativamente barato e com um baixo ponto de fusão.…”

Resumo Nanopartículas de ferrita de manganês (MnFe2O4) foram dispersas em parafina e as propriedades físicas do compósito resultante foram investigadas por ressonância ferromagnética (RFM). Os resultados mostraram que a dispersão em quantidades moderadas de parafina aumenta significativamente a anisotropia magnética das nanopartículas de ferrita, um resultado que pode ser de interesse para aplicações práticas do compósito.
