TL;DR: In this article, the complex nature of magnetic ordering in the spinel Co2TiO4 was investigated by analyzing the temperature and magnetic field dependence of its magnetization (M), specific heat (C-p), and ac magnetic susceptibilities.
Journal ArticleDOI

P. Pramanik,Subhash Thota,Sobhit Singh,D. C. Joshi,Bruno Weise,Anja Waske,Mohindar S. Seehra +6 more
TL;DR: The results and their analysis from the detailed investigations of the effects of Cu doping on the electronic structure and magnetic properties of the spinel O4.4 support the existence of glassy states in nanosize samples and investigate the temperature and composition dependence of the hysteresis loop parameters.

TL;DR: In this paper, the low-temperature anomalous magnetic behavior of ferrimagnetic spinels cobalt orthotitanate (Co2TiO4), which exhibits magnetic compensation behavior across 3174
Journal ArticleDOI
Antiferromagnetism, spin-glass state, H-T phase diagram, and inverse magnetocaloric effect in Co2RuO4.
Sayandeep Ghosh,D. C. Joshi,P. Pramanik,Suchit Kumar Jena,Suresh Pittala,Tapati Sarkar,Mohindar S. Seehra,Subhash Thota +7 more
TL;DR: Investigations of the temperature, magnetic field, frequency and frequency dependence of the ac-magnetic susceptibilities and dc-magnetization covering the temperature range T = 2 K-400 K and H up to 90 kOe show that Co2RuO4 exhibits an antiferromagnetic (AFM) transition at T N ∼ 15.2 K and the observed time-dependence of M(t) is supportive of the spin-glass state.
