Exchange bias with Fe substitution in LaMnO_3
M. Patra, K. De, S. Majumdar +1
The exchange bias (EB) in LaMn_{0.7}Fe_{0.3}O_3 is observed by the negative shift and training effect of the hysteresis loops, while the sample was cooled in external magnetic fiel…
Inhomogeneous phase separation and domain wall dynamics in the orthorhombically distorted La_{0.87}MnO_x
K. De, S. Majumdar, S. Giri
We observe the interesting magnetization and resistivity results in the orthorhombically distorted self doped manganite, La_{0.87}MnO_x. A significant irreversibility between zero-…
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…
Interparticle interaction and size effect in polymer coated magnetite nanoparticles
M. Thakur, K. De, S. Giri +3
Magnetization and Mossbauer studies have been performed on the polymer coated magnetite nanoparticles with particle size from 5.1 to 14.7 nm. The maximum in the temperature depende…
