Effect of spin glass frustration on exchange bias in NiMn/CoFeB bilayers
Sagarika Nayak, Palash Kumar Manna, Braj Bhusan Singh +1
Exchange bias in ferromagnetic/antiferromagnetic systems can be explained in terms of various interfacial phenomena. Among these spin glass frustration can affect the magnetic prop…
Temperature and field evolution of site-dependent magnetism in -FeO nanoparticles
Richard Jones, Rachel Nickel, Palash K. Manna +2
8~nm epsilon-Fe2O3 nanoparticles exhibit a spin reorientation transition that begins at 150 K which is a hallmark of this unique iron-oxide polymorph. We find that the change from…
Exchange bias in Fe/Ir20Mn80 bilayers: Role of spin-glass like interface and bulk antiferromagnet spins
Sagarika Nayak, Palash Kumar Manna, Thiruvengadam Vijayabaskaran +2
We have performed magnetic measurements like temperature (T), cooling field (HFC) dependence of exchange bias (EB) and training effect to investigate the magnetic nature of the int…
Exchange Bias in BiFe_{0.8}Mn_{0.2}O_3 Nanoparticles with an Antiferromagnetic Core and a Diluted Antiferromagnetic Shell
P. K. Manna, S. M. Yusuf, R. Shukla +1
We have observed conventional signature of exchange bias (EB), in form of shift in field-cooled (FC) hysteresis loop, and training effect, in BiFe0.8Mn0.2O3 nanoparticles. From neu…
Enhanced grain surface effect on magnetic properties of nanometric La0.7Ca0.3MnO3 manganite : Evidence of surface spin freezing of manganite nanoparticles
P. Dey, T. K. Nath, P. K. Manna +1
We have investigated the effect of nanometric grain size on magnetic properties of single phase, nanocrystalline, granular La0.7Ca0.3MnO3 (LCMO) sample. We have considered core-she…
