Ferroelectric order associated with an ordered occupancy at the octahedral site of the inverse spinel structure of multiferroic NiFe2O4
J. K. Dey, A. Chatterjee, S. Majumdar +4
We report a ferroelectric order at ~ 98 K for NiFe2O4, which carries an inverse spinel structure with a centrosymmetric Fd3m structure at room temperature. The value of spontaneous…
Exchange bias effect in alloys and compounds
S Giri, M Patra, S Majumdar
The phenomenology of exchange bias effects observed in structurally single-phase alloys and compounds but composed of a variety of coexisting magnetic phases such as ferromagnetic,…
Magnetic and magnetoresistive properties of cubic Laves phase HoAl single crystal
M. Patra, S. Majumdar, S. Giri +2
We report the magnetization () and magnetoresistance (MR) results of HoAl single crystals oriented along and directions. Although HoAl has cubic Laves ph…
Exchange bias effect and intragranular magnetoresistance in Nd$_{0.84}Sr_{0.16}CoO_3
M. Patra, S. Majumdar, S. Giri
Electrical transport properties as a function of magnetic field and time have been investigated in polycrystalline, Nd_{0.84}Sr_{0.16}CoO_3. A strong exchange bias (EB) effect is o…
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…
Exchange bias effect in the phase separated Nd_{1-x}Sr_{x}CoO_3 at the spontaneous ferromagnetic/ferrimagnetic interface
M. Patra, M. Thakur, S. Majumdar +1
We report the new results of exchange bias effect in Nd_{1-x}Sr_{x}CoO_3 for x = 0.20 and 0.40, where the exchange bias phenomenon is involved with the ferrimagnetic (FI) state in…
