Structural, magnetic and magneto-resistance properties of La0.88Ca0.12MnO3 single crystals

La(0.88)Ca(0.12)MnO(3) single crystals of high quality have been prepared by using floating zone technique. Their cornposition and structure are verified using X-ray diffraction and EDAX. The temperature dependence of the resistance along ab-plane and c-axis has been measured in the temperature range 77 K to roorn temperature in the magnetic fields up to 8 T. The R-T data along ab-plane and c-axis shows a similar behaviour and it is the characteristics of insulating behaviour having the resistance 0.7 MQ at 90 K and 16.1 Q at 300 K. Tile insulating behaviour persists under the inagnetic field tip to H = 8 T. There is no resistance peak or electronic transition over the whole ternperature range studied. However, there is a notable change of resistance at about 120 K_ seemingly relatcd to parannagnetic insulator to ferroinagnetic insulator transition and is confirined by magnetization measurement transition at a temperature T, = 122 K. The sharp peak around the same temperature in the heat capacity measurement indicates the onset of long range ordering. The magnetoresi stance measured at different magnetic fields shows sirnilar kind of behaviour with sonne rnarginal change in the inagnitude along ab-plane and c-axis.
