Abstract: The transport, magnetic and thermal properties of La0.88Ca0.12MnO3 single crystals have been studied using various experimental techniques. The resistivity measurement shows the characteristics of semiconducting behaviour having the resistivity 6.9 MΏcm at 90K and 31.5 Ώcm at 296K. There is no resistivity peak or electronic transition over the whole temperature range studied. However, there is a notable change of resistivity at about 115 K, seemingly related to paramagnetic insulator to ferromagnetic insulator transition. The ac susceptibility measurement confirms that this material shows paramagnetic insulator to ferromagnetic insulator transition with Tc = 117.5 K. The sharp peak around the same temperature in the heat capacity measurement indicates the onset of long range ordering.
