​Abstract
Single crystals of La0.9Pb0.1MnO3 (LPMO) were grown from the flux solution of PbF2 and PbO. The X ray back reflection Laue pattern and powder diffraction were carried out to determine quality and structure of the grown LPMO single crystals.  Surface morphology and the chemical composition of the grown crystals were studied using SEM and EDX. Resistivity measurement was performed in a magnetic field of 0T and 6T and its magneto-resistance value was determined. Hysteresis was measured using magnetic field parallel and perpendicular to ‘ab’ plane at 10K. DC magnetization was carried out between the temperature ranges 10 K-300 K. The magnetic field dependence of ZFC and FC condition magnetization were measured with the field at 20 Oe and 500 Oe.

​​Keywords: Olossal magnetoresistance; Single crystals; Surface morphology; Cluster glass.
