Phase transitions and rare-earth magnetism in hexagonal and orthorhombic DyMnO single crystals
S Harikrishnan, S Roessler, C M Naveen Kumar +5
The floating-zone method with different growth ambiances has been used to selectively obtain hexagonal or orthorhombic DyMnO single crystals. The crystals were characterized…
Low Temperature Transport and Specific Heat Studies of Nd_{1-x}Pb_{x}MnO_{3} Single Crystals
N. Ghosh, U. K. Roessler, K. Nenkov +3
Electrical transport and specific heat properties of Nd_{1-x}Pb_{x}MnO_{3} single crystals for 0.15 < x 0.5 have been studied in low temperature regime. The resistivity in the ferr…
Polaronic state and nanometer-scale phase separation in colossal magnetoresistive manganites
Sahana Roessler, S. Ernst, B. Padmanabhan +4
High resolution topographic images obtained by scanning tunneling microscope in the insulating state of Pr0.68Pb0.32MnO3 single crystals showed regular stripe-like or zigzag patter…
Colossal electroresistance in ferromagnetic insulating state of single crystal NdPbMnO
Himanshu Jain, A. K. Raychaudhuri, Nilotpal Ghosh +1
Colossal electroresistance (CER) has been observed in the ferromagnetic insulating (FMI) state of a manganite. Notably, the CER in the FMI state occurs in the absence of magnetores…
Influence of dopant concentration on the structure and physical properties of NdPbMnO single crystals
Nilotpal Ghosh, Suja Elizabeth, H. L. Bhat +3
The structure of NdPbMnO crystals is determined by single crystal X-ray diffraction. Substitution of Pb at the Nd site results in structural phase change from t…
Critical properties of the double exchange ferromagnet Nd0.4Pb0.4MnO3
M. Sahana, U. K. Roessler, Nilotpal Ghosh +6
Results of a study of dc-magnetization M(T, H), performed on a Nd0.6Pb0.4MnO3 single crystal in the temperature range around T_C (Curie temperature) which embraces the critical reg…
