We report near room temperature ferromagnetic as well as low temperature antiferromagnetic correlations in Mn doped Cobalt Tellurate (CMTO) solid solutions using thorough magnetization studies. For all the composition the solid solutions show not only short range robust FM order at 185 K but also show long range enhanced AFM order less than or equal to 45 K. Scaling of inverse magnetic susceptibility data provide clear indication of Griffiths like FM phase extended over large thermal region and…

Observation of Griffiths-like phase in Y2CrMnO6 perovskites
Abstract Temperature-dependent magnetic measurements indicate a magnetic transition (TC) at 33 K in monoclinic Y2CrMnO6. The presence of different cations Cr 2+, Cr3+, Mn3+, and Mn4+ leads to
Exotic magnetic properties and enhanced magnetoelectric coupling in Fe3O4-BaTiO3 heterostructures
Abstract In the present work, magnetoelectric composites of Fe3O4 and BaTiO3 were successfully synthesized with 0–3 and 1–3 connectivity. In Fe3O4-BaTiO3 composites with 1–3 connectivity, the M-H

Griffiths singularities and magnetoresistive manganites
The large, so-called colossal magnetoresistivity of doped LaMnO 3 has attracted considerable attention, but is only one unusual feature of the ferromagnetic transition in these compounds. We examine
A Griffiths-like phase in antiferromagnetic R0.5Eu0.5MnO3 (R = Pr, Nd, Sm).
TLDR
A Griffiths-like phase in isovalent doped rare-earth manganites is reported and the presence of short range ferromagnetically correlated spin clusters is observed above the antiferromagnetic transition temperature.
Observation of a Griffiths-like phase in the magnetocaloric compound Tb5Si2Ge2.
TLDR
It is suggested that the Griffiths-like state is originated by local disorder within the crystallographic structure, stabilized and enhanced by competing intralayer and interlayer magnetic interactions, which promote segregation of nanometric regions with ferromagnetic interactions.

The complex metal oxide Mn(3)TeO(6) exhibits a corundum related structure and has been prepared both in forms of single crystals by chemical transport reactions and of polycrystalline powders by a
