Exchange bias effect involved with tunneling magnetoresistance in polycrystalline La_{0.88}Sr_{0.12}CoO_3
M. Patra, S. Majumdar, S. Giri
We report the exchange bias (EB) effect along with tunneling magnetoresistance (MR) in polycrystalline La_{0.88}Sr_{0.12}CoO_3. Analogous to the shift in the magnetic hysteresis lo…
Intragrain electrical inhomogenities and compositional variation of static dielectric constant in LaMn_{1-x}Fe_xO_3
A. Karmakar, S. Majumdar, S. Patnaik +1
Bulk dc resistivity and dielectric constant measurements with temperature and frequency have been performed in LaMn_{1-x}Fe_xO_3 (0 <= x <= 1.0) as a result of Fe substitution both…
Polaron relaxation and hopping conductivity in LaMnFeO
A. Karmakar, S. Majumdar, S. Giri
Dc and ac transport properties as well as electric modulus spectra have been investigated for the samples LaMnFeO with compositions 0 1.0. The bulk…
Magnetic field induced metastability in the self-doped manganites
K. De, S. Majumdar, S. Giri
We observe an interesting scenario of field induced metastabilities in the resistivity measurements. The resistivity exhibits a bifurcation of zero-field cooled and field-cooled (F…
