Nature Of Magnetic Ordering In Cobalt‐Based Spinels, Subhash Thota, Sobhit Singh Jan 2017

Nature Of Magnetic Ordering In Cobalt‐Based Spinels, Subhash Thota, Sobhit Singh

Faculty & Staff Scholarship

In this chapter, the nature of magnetic ordering in cobalt‐based spinels Co3O4, Co2SnO4, Co2TiO4, and Co2MnO4 is reviewed, and some new results that have not been reported before are presented. A systematic comparative analysis of various results available in the literature is presented with a focus on how occupation of the different cations on the A‐ and B‐sites and their electronic states affect the magnetic properties. This chapter specifically focuses on the issues related to (i) surface and finite‐size effects in pure Co3O4, (ii) magnetic‐compensation effect, (iii) co‐existence of ferrimagnetism and spin‐glass‐like ordering ...
