Summary: In this work, the Mn2SiX4 olivines (X=S, Se) were studied using magnetic susceptibility, X-ray and neutron diffraction. The crystal structures of Mn2SiS4 and Mn2SiSe4 were determined using synchrotron X-ray, neutron diffraction, and X-ray total scattering data. It was found that the Mn triangle forming the sawtooth lattice is isosceles in both compounds. The temperature evolution of magnetic susceptibility showed anomalies below 83 K and 70 K for Mn2SiS4 and Mn2SiSe4, respectively, indicating the presence of magnetic ordering. Neutron diffraction measurements revealed that the magnetic space groups of Mn2SiS4 and Mn2SiSe4 are Pnma and Pnm ' a ', respectively.

Summary: The origins of the giant piezoresponse in relaxor ferroelectrics have been successfully understood through the growth and analysis of Ho-doped Pb(Mg-1/Nb-3(2/3))O-3-PbTiO3 (Ho-PMNT) single crystals. It was found that the giant piezoelectric response originates from the composition near the tricritical triple point of different structural phases. The study also analyzed the nanoscale heterogeneities and their connection to local polarization.

Summary: In this research, terbium-doped strontium aluminate SrAl4O7 samples were synthesized using the solid-state synthesis method. The samples were characterized using X-Ray powder diffraction (XRD) and photoluminescence (PL) measurements. The results showed that all the samples exhibited yellowish-green emission with the highest peak at 542 nm, attributed to the D-5(4)-> F-7(5) transition. The highest emission intensity was observed in the Sr0.98Al4O7:Tb-0.02 sample, while higher doping levels resulted in a decrease in PL intensities due to concentration quenching. The PL properties of samples with additional IA group ions for charge compensation were also measured.
