Insensitivity of magnetic anomalies in Sr3NiPtO6 to positive and negative pressures
S. Narayana Jammalamadaka, Niharika Mohapatra, Karthik K Iyer +1
The compound, Sr3NiPtO6, belonging to a K4CdCl6-type rhombohedral structure, has been reported not to exhibit magnetic ordering at least down to 1.8 K, despite a relatively large v…

Magnetic ordering in the fine particles of some bulk Pauli-paramgnets
Sitikantha D. Das, S. Narayana Jammalamadaka, Kartik K Iyer +1
Fine particles of some of the extensively studied 'enhanced' Pauli paramagnets - LuCo2, ScCo2, ZrCo2 and CeRu2Si2, have been prepared by high-energy ball-milling and investigated f…

Enhancement of positive magnetoresistance following a magnetic-field-induced ferromagnetic transition in an intermetallic compound, Tb5Si3
S. Narayana Jammalamadaka, Niharika Mohapatra, Sitikantha D Das +1
We report the existence of a field-induced ferromagnetic transition in the magnetically ordered state (<69 K) of an intermetallic compound, Tb5Si3, and this transition is distinctl…
