Structural, transport, magnetic and thermal properties of La0.7Ca0.24Sr0.06MnO3 single crystal

La(0.7)Ca(0.24)Sr(0.06)sMnO(3) single crystals with high quality have been prepared by using floating zone technique. The structural,. transport, magnetic and thermal properties of the hole doped La0.7Ca0.24Sr0.06MnO3 single crystal. have been studied using various experimental techniques. The resistivity data shows the metal to insulator transition (MI) occurs at T-MI = 281 K along the c-axis and T-MI = 270 K along the ob-plane. It is observed that the T-MI data is higher along the c-axis as compared to that in the ob-plane, thus indicating more favourable hoping of elections is along (lie c-axis. This MI. transition and large magnetoresistance peak 79 % is closely near to the ferromagnetic - paramagnetic transition T-c. which was confirmed from the magnetization data (at similar to 275 K), it was also confirmed from the ac susceptibility, data (at - 275 K) and (lie specific heat data (at similar to 270 K), which in term is indicative of lite onset of long range order. The entropy change associated with this transition is found to be 2.3 J/mol K. For bolometric applications point of view, the temperature coefficient of resistance (TCR) along ab-plane is found similar to 23 % K-1.
