“…The electromagnetic wave absorption reaches 95% at the highest peak frequency 14.1 GHz in the sample of x = 0.3 having sample thickness of relatively thin about 1.5 mm. The RL value of this sample is comparable with that of the similar type sample, which previously reported (Zhou e al., 2009;Zhang & Cao, 2012). Nevertheless, the results of the current study indicate superior to the previous one where the absorption performance can be similar but the sample thickness of current finding is much less.…”

“…The maximum reflection loss was 27.67 dB at a 10.97 GHz frequency, which was obtained from a sample thickness of 2mm. The absorption bandwidth was above 6 dB at a frequency 6.80 GHz (Zhang & Cao, 2012). Additionally, Zhou et al (2009) reported the successful synthesis of a modified of manganite-based compound.…”

“…Manganite-based perovskite is another electromagnetic wave absorbing material that has been also developed (Zhang & Cao, 2012;Zhou et al, 2009;Cheng et al, 2010). Manganite-based perovskite is one of the potential candidate materials for microwave absorber applications due to its high permittivity and permeability.…”

“…Manganite-based perovskite is one of the potential candidate materials for microwave absorber applications due to its high permittivity and permeability. Zhang & Cao (2012) succeeded in synthesizing transition metal (TM)-doped La0.7Sr0.3Mn1−xTMxO3± δ (TM: Fe, Co, or Ni) for microwave absorbing materials. La0.7Sr0.3Mn0.8Fe0.2O3± δ has shown good properties for microwave absorption.…”

This paper reports on the magnetic properties and electromagnetic characterization of La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1-0.8). The La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1-0.8) materials were prepared using a mechanical alloying method. All the materials were made of analytical grade precursors of BaCO3, Fe2O3, MnCO3, TiO2, and La2O3, which were blended and mechanically milled in a planetary ball mill for 10h. The milled powders were compacted and subsequently sintered at 1000°C for 5h. All the sintered samples showed a fully crystalline structure, as confirmed using an X-ray diffractometer. It is shown that all samples consisted of LaMnO3 based as the major phase with the highest mass fraction up to 99% found in samples with x < 0.3. The mass fraction of main phase in doped samples decreased in samples with x > 0.3. The hysteresis loop derived from magnetic properties measurement confirmed the present of hard magnetic BaFe12O19 phase in all La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1-0.8) samples. The results of the electromagnetic wave absorption indicated that there were three absorption peaks of ~9 dB, ~8 dB, and ~23.5 dB, respectively, at respective frequencies of 9.9 GHz, 12.0 GHz, and 14.1 GHz. After calculations of reflection loss formula, the electromagnetic wave absorption was found to reach 95% at the highest peak frequency of 14.1 GHz with a sample thickness of around 1.5 mm. Thus, this study successfully synthesized a single phase of La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1-0.8) for the electromagnetic waves absorber material application.

The perovskite structure La1−xSr(or Sm)xMnO3±δ (x = 0, 0.25) powders were successfully fabricated by the traditional solid state reaction method. The influences of Sr2+ or Sm3+ doping on the static and dynamic magnetic performance were investigated. The resonance phenomena could be attributed to natural resonance and exchange resonance. The substitution of Sr2+ or Sm3+ into La3+ could greatly influence the resonance frequency. Furthermore, the microwave absorption performance of LaMnO3 was improved after the incorporation of Sr2+ or Sm3+. It is obtained that Sr2+ doped LaMnO3 had superior performance compared with that of Sm3+ doped LaMnO3. The maximum reflection loss was −30.0 dB at 13.968 GHz with a thickness of 1.6 mm. The microwave absorption performance was attributed to both the dielectric and magnetic losses.
