La-Ca-Co substituted M-type Sr-hexaferrites (Sr0.3Ca0.4La0.3Fe9.8Co0.2O19-δ) were prepared by a solid-state reaction using two different procedures, where the SiO2 additive was mixed either before calcination (pre-Si) or after calcination (post-Si).

A wideband electromagnetic (EM) wave absorber for the X-band (8–12 GHz) is designed using M-type hexaferrite, SrFe12-2xCoxTixO19 (x = 1.1, 1.2, 1.25, and 1.3)–CNT (0–3 wt%)–epoxy (10 wt%) composites. As x increases from 1.1 to 1.3, the ferrom

Cubic CdS epilayers were grown on (100) GaAs substrate by hot-wall epitaxy. X-ray diffraction and photoluminescence measurements revealed that the hexagonal phase was dominant in the layers grown at low temperatures, and the cubic phase became domina

Resonant Raman scattering spectra for ZnS epilayers grown by hot-wall epitaxy have been studied extensively. With a 325 nm He–Cd laser as the excitation source, three resonant Raman lines were observed in photoluminescence spectra. The temperature
