Impact of Zn addition on structural, morphological, and magnetic properties of thermally annealed Li–Zn nanoferrite

The effect of Zn addition on cationic distribution, structural and magnetic properties of nanocrystalline Li-Zn ferrites are reported. Xray diffraction confirms the formation of spinel nanoferrites with an average grain diameter of 34 -82 nm. The…

Huge laser-induced modulation of the ferromagnetic fraction in the antiferro-ferromagnetic mixed phase of FeRh

Among magnetic materials near equi-atomic FeRh alloys, with their antiferromagnetic (AF) to ferromagnetic (FM) magneto-structural hysteretic transition near room temperature, were studied long ago in bulk form [Kouvel, JAP 1962, Lewis, J. Phys.D…
