Potassium Zinc Sulphate Hydrate (PZSH) crystals have been grown by slow evaporation technique at room temperature. The single crystal X-ray diffraction results reveal that PZSH belong to monoclinic system with space group P21/C. The presences of various functional groups of the PZSH have been confirmed by FTIR analysis. EDAX result reveals the presence of PZSH elements in the sample. The optical transparency and optical band gap of the PZSH are determined by UV-Visible analysis. PZSH is found to be optically transparent in the entire UV-Visible region. The NLO property of the PZSH has been measured by Kurtz Perry powder method and PZSH has been found to exhibit second harmonic generation.The second harmonic generation efficiency of PZSH is equal to 0.49 times than that of KDP. The thermal stability and decomposition process of PZSH are studied by TGA and DTA. PZSH is found to have poor thermal stability.Saturation magnetization (Ms), coercive field (Hc) and remanent magnetization (Mr) of PZSH are measured by VSM analysis.
