Disorder driven cluster glass state in a geometrically frustrated hexagonal perovskite
Shruti Chakravarty, Øystein Slagtern Fjellvåg, Arpan Bhattacharyya +2
We report the observation of cluster glass-like properties in a double perovskite ruthenate BaCoRuO through structural (neutron and synchrotron X-ray diffraction), magnetic…
Topological Phase Transitions Induced by Varying Topology and Boundaries in the Toric Code
Amit Jamadagni, Arpan Bhattacharyya
One of the important characteristics of topological phases of matter is the topology of the underlying manifold on which they are defined. In this paper, we present the sensitivity…
Investigations of the heterometallic Ludwigite NiAlBO
Jitender Kumar, Deepak John Mukkattukavil, Arpan Bhattacharyya +1
We present magnetic, thermodynamic, dielectric and structural investigations on the aluminoborate NiAlBO, belonging to the ludwigite family. Room temperature structural…
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…
Robustness of Topological Order in the Toric Code with Open Boundaries
Amit Jamadagni, Hendrik Weimer, Arpan Bhattacharyya
We analyze the robustness of topological order in the toric code in an open boundary setting in the presence of perturbations. The boundary conditions are introduced on a cylinder,…
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…
A reentrant superspin glass state and magnetization steps in the oxyborate Co2AlBO5
Jitender Kumar, Soumendra Nath Panja, Deepak John +3
An oxyborate Co2AlBO5 belonging to the ludwigite family is investigated using structural, thermodynamic, dielectric and magnetic measurements. Magnetic measurements indicate that t…
