Electrical-transport, magnetoresistance and magnetic properties of La 0.7 Ca 0.3 MnO 3 and La 0.7 Ca 0.24 Sr 0.06 MnO 3 single crystals Tejas M. Tank, Ashish Bodhaye, Ya. M. Mukovskii, S. P. Sanyal Aip Conference Proceedings, 2015 We report the electrical-transport, magnetoresistance and magnetic properties of the hole doped La0.7Ca0.3MnO3 (LCMO) and La0.7Ca0.24Sr0.06MnO3 (LCSMO) single crystals. It was prepared using floating zone technique. The resistivity data shows the metal to insulator transition (TMI) occurs at 211 K along c-axis and TMI = 185 K the ab-plane for LCMO and TMI = 290 K along the c-axis and TMI = 280 K along the ab-plane for LCSMO single crystals. It is observed that the TMI is higher along the c-axis as compared to that in the ab-plane, consequently signifying more favorable hoping of electrons is along the c-axis. The ac-susceptibility measurement shows that this material exhibits ferromagnetic to paramagnetic transition temperature (TC) at 206 K for LCMO and TC = 277 K for LCSMO single crystals. For magnetic memory device application point of view, the sample shows the maximum MR of 98% for LCMO and 80% for LCSMO single crystals at 8T applied magnetic field. Doping small amount of Sr (0.06%) reveals that the ...
Transport, magnetic, and thermal properties of La0.7Ca 0.24Sr0.06MnO3 single crystal Tejas M. Tank, Ashish Bodhaye, Ya M. Mukovskii, Sankar P. Sanyal Advances in Condensed Matter Physics, 2013 We report the transport, magnetic, and thermal properties of La0.7Ca0.24Sr0.06MnO3single crystal. It was prepared using floating zone technique used under oxygen pressure of 1 bar with a typical growth rate of 1 mm/hr. The resistivity data shows the metal to insulator transition (M-I) occuring atTMI=290 K along thec-axis and atTMI=280 K along theab-plane. It is observed that theTMIis higher along thec-axis as compared to that in theab-plane, thus indicating that more favorable hoping of electrons is along thec-axis. From bolometric application point of view, the temperature coefficient of resistance (TCR) is found to be ~28% K−1. Theac-susceptibility measurement shows that this material exhibits ferromagnetic to paramagnetic transition temperature (TC) 277 K. Sharp peak around this temperature in heat capacity data indicates the onset of long-range ordering. The entropy change associated with this transition is found to be 2.3 J/mol K.

Structural, transport, magnetic and thermal properties of la 0.7Ca0.24Sr0.06MnO3 single crystal Ashish Bodhaye, Sankar P. Sanyal, Y. M. Mukovskii, P. Predeep, S. Prasanth, A. S. Prasad Aip Conference Proceedings, 2008 La0.7Ca0.24Sr0.06MnO3 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 TMI = 281 K along the c‐axis and TMI = 270 K along the ab‐plane. It is observed that the TMI data is higher along the C‐axis as compared to that in the ab‐plane, thus indicating more favourable hoping of electrons is along the c‐axis. This MI transition and large magnetoresistance peak 79% is closely near to the ferromagnetic—paramagnetic transition Tc, which was confirmed from the magnetization data (at ∼275 K), it was also confirmed from the ac susceptibility data (at ∼275 K) and the specific heat data (at ∼270 K), which in term is indicative of the onset of long range order. The entropy change associated with this transition is found to be 2.3 J/mol K....
