Quasi-static remanence as a generic-feature of spin-canting in Dzyaloshinskii-Moriya Interaction driven canted-antiferromagnets
Namrata Pattanayak, Arun Kumar, A. K Nigam +3
We consistently observe a unique pattern in remanence in a number of canted-antiferromagnets (AFM) and piezomagnets. A part of the remanence is in nature an…
Dielectric and Raman Spectroscopy in Hematite crystallites across the Morin Transition
Namrata Pattanayak, Jitender Kumar, Partha Pratim Patra +2
We report complex dielectric and Raman spectroscopy measurements in four samples of - FeO, consisting of crystallites which are either hexagonal shaped plates or cuboids…
Non-van der Waals honeycomb antiferromagnet SrRuO down to a few layers
Suvidyakumar Homkar, Bharat Chand, Shatruhan Singh Rajput +8
The current family of experimentally realized two-dimensional magnetic materials consist of 3 transition metals with very weak spin-orbit coupling. In contrast, we report a new…
Weak Ferromagnetism and Time-Stable Remanence in Hematite: Effect of Shape, Size and Morphology
Namrata Pattanayak, Arpan Bhattacharyya, Shruti Chakravarty +1
We have recently established that a number of Dzyaloshinskii-Moriya interaction driven canted antiferromagnets or weak ferrromagnets (WFM) including hematite exhibit an ultra-slow…
Quasi Static Remanence in Dzyaloshinskii-Moriya Interaction driven Weak Ferromagnets and Piezomagnets
Namrata Pattnayak, Arpan Bhattacharyya, A. K. Nigam +2
We explore remanent magnetization () as a function of time and temperature, in a variety of rhombohedral antiferromagnets (AFM) which are also weak ferromagnets (WFM) and piezom…
Interface driven magnetoelectric effects in granular CrO2
A. Bajpai, P. Borisov, S. Gorantla +5
Antiferromagnetic and magnetoelectric Cr2O3-surfaces strongly affect the electronic properties in half metallic CrO2. We show the presence of a Cr2O3 surface layer on CrO3 grains b…
