Temperature dependence of Magnetic properties in Nanocrystalline copper ferrite thin films
P. D. Kulkarni, Shiva Prasad, N. Venkataramani +5
The copper ferrite thin films have been deposited by RF sputtering at a 50W rf power. The As-deposited films are annealed in air at C and then slow cooled. The As-depo…
The High Field Magnetization in the RF Sputter Deposited Copper Ferrite Thin Films
P. D. Kulkarni, Shiva Prasad, N. Venkataramani +5
Copper ferrite thin films were deposited on amorphous quartz substrates. The as deposited films were annealed in air and either quenched or slow cooled. Magnetization studies were…
Superparamagnetism in Nanocrystalline Copper Ferrite Thin Films
P. D. Kulkarni, R. P. R. C. Aiyar, Shiva Prasad +6
The rf sputtered copper ferrite films contain nanocrystalline grains. In these films, the magnetization does not saturate even in high magnetic fields. This phenomenon of high fiel…
Search and identification of repeated magnetic compensation in Nd(1-x)R(x)Al(2) (R = Gd, Tb) series
P. D. Kulkarni, A. Thamizhavel, S. Ramakrishnan +1
We undertook investigations in polycrystalline R(x)R'(1-x)Al(2) alloys, in particular, explored the stoichiometries, Nd(0.8)Gd(0.2)Al(2) and Nd(0.8)Tb(0.2)Al(2), to study the magne…
Field induced changes across magnetic compensation in Pr(1-x)Gd(x)Al(2) alloys
P. D. Kulkarni, A. K. Nigam, S. Ramakrishnan +1
The magnetic compensation phenomenon has been explored in the Pr(1-x)Gd(x)Al(2) series. The contributions from Pr and Gd moments compensate each other at a specific temperature in…
Sign reversal in the exchange bias and the collapse of hysteresis width across the magnetic compensation temperature in a single crystal of Nd0.75Ho0.25Al2
Prasanna D. Kulkarni, A. Thamizhavel, V. C. Rakhecha +4
In the admixed Nd0.75Ho0.25Al2 system, magnetic moments of Nd and Ho occupying the same crystallographic site are antiferromagnetically coupled and the chosen stoichiometry display…
Exchange bias and its phase reversal in the zero magnetization admixed rare earth intermetallics
Prasanna D. Kulkarni, S. Venkatesh, A. Thamizhavel +3
Exchange bias effect is an important attribute in several device applications. Traditionally, it is discussed as a form of exchange anisotropy at the interface between the ferromag…
Repeated magnetic compensation behaviour in Nd0.75Gd0.25Rh3B2 alloy having hexagonal structure and planar anisotropy
Prasanna D. Kulkarni, U. V. Vaidya, V. C. Rakhecha +5
The results of dc and ac magnetization, electrical resistance and heat capacity studies in an admixed rare earth alloy Nd0.75Gd0.25Rh3B2, which is close to the zero magnetization l…
