New nanosized Gd-Ho-Sm doped M-type strontium hexaferrite for water treatment application: experimental and theoretical investigations.

In this paper, rare-earth doped M-type strontium hexaferrite magnetic nanoparticles SrHo Gd Sm FeO ( = = = 0.01) have been prepared by the sol-gel combustion method for the first time. The properties of the material were investigated using XRD, FTIR spectroscopy, Raman spectroscopy, SEM, UV-Vis spectroscopy, and VSM.
