Field-induced single-ion magnet based on a quasi-octahedral Co(ii) complex with mixed sulfur–oxygen coordination environment

Dalton Transactions, 2021
Novel (pipH2)[Co(TDA)2] is a rare example of a quasi-octahedral Co(ii) complex with mixed sulfur-oxygen environment exhibiting strong “easy-plane” type magnetic anisotropy and demonstrating field-induced single-ion magnet (SIM) behavior.

Iron environment non-equivalence in both octahedral and tetrahedral sites in NiFe[sub 2]O[sub 4] nanoparticles: Study using Mössbauer spectroscopy with a high velocity resolution [PDF]

AIP Conference Proceedings, 2012
Mossbauer spectrum of NiFe2O4 nanoparticles was measured at room temperature in 4096 channels. This spectrum was fitted using various models, consisting of different numbers of magnetic sextets from two to twelve. Non-equivalence of the 57Fe microenvironments due to various probabilities of different Ni2+ numbers surrounding the octahedral and ...
