We study the behavior of the exchange bias (EB) and the blocking temperature in an antiferromagnetic FeVO4–ferrimagnetic Fe3O4 nanocomposite system upon annealing in Ar atmosphere. Surprisingly, the blocking temperature of post-annealed samples inc

We have synthesized porous Li 2 FeSiO 4 /C nanocomposites by two different routes such as sol-gel (Li 2 FeSiO 4 /C-SG) and solvothermal (Li 2 FeSiO 4 /C-ST) using block copolymer pluronic (P123) as both in-situ carbon source and structure directing a
