Magnetic study of an amorphous conducting polyaniline
Debangshu Chaudhuri, Ashwani Kumar, D. D. Sarma +3
We show that newly found BF3-doped polyaniline, though highly conducting, remains amorphous. Magnetic studies reveal many unusual properties, while suggesting that the intrinsic co…
An Electron Paramagnetic Resonance Study of Electron-Hole Asymmetry in Charge Ordered Pr_1-x Ca_xMnO_3 (x=0.64, 0.36)
Janhavi P. Joshi, A. K. Sood, S. V. Bhat +2
We present and compare the results of temperature-dependent electron paramagnetic resonance (EPR) studies on Pr_1-x Ca_xMnO_3 for x = 0.64 which is electron-doped with those on the…
Electron paramagnetic resonance studies of the insulating ferromagnetic manganite Nd_0.8Pb_0.2MnO_3 above the transition temperature
Anika Kumar, Nilotpal Ghosh, Janhavi P. Joshi +2
Single crystals of Nd_{1-x}Pb_{x}MnO_{3} with x=0.2 are grown by high temperature solution growth technique using PbO-PbF_{2} flux. Magnetization studies on the samples show a tran…
Electron Paramagnetic Resonance Study of Phase Segregation in NdSrMnO
Janhavi P. Joshi, A. K. Sood, S. V. Bhat +2
We present results of an electron paramagnetic resonance (EPR) study of NdSrMnO with x = 0.5 across the paramagnetic to ferromagnetic, insulator to metal transition…
Non-resonant microwave absorption studies of superconducting MgB_2
Janhavi P. Joshi, Subhasis Sarangi, A. K. Sood +2
Non-resonant microwave absorption(NRMA) studies of superconducting MgB_2 at a frequency of 9.43 GHz in the field range -50 Gauss to 5000 Gauss are reported. The NRMA results indica…
Temperature-dependent electron paramagnetic resonance studies of charge ordered Nd_0.5Ca_0.5MnO_3
Janhavi P. Joshi, Rajeev Gupta, A. K. Sood +3
We report Electron Paramagnetic Resonance measurements on single crystalline and powder samples of Nd_0.5Ca_0.5MnO_3 across the charge-ordering transition at T_co=240 K down to the…
