Frustration-induced degenerate spin state with up-up-down-down ordering in corner-connected Heisenberg square-plaquettes
Pritam Manna, A. K. Bera
We investigate frustrated magnetism of a corner-connected square plaquette Heisenberg model with exchange interactions along the edges , along inter-plaquette links ,…
Neutron scattering evidence for two-dimensionally coupled spin-dimerized antiferromagnetic lattice in α-Cu2P2O7
B. Ghanta, K. S. Chikara, M. Ghanathe +3
The microscopic magnetic model of the low-dimensional quantum magnet alpha-Cu2P2O7 has remained controversial. We present a comprehensive study of its magnetic ground state and exc…
Anomalous behavior of native point defects in C2-ordered antiferromagnet -MnO
Archana Sharma, Brahmananda Chakraborty
-MnO is an emerging material for electronic, optoelectronic, and energy applications, owing to its structural flexibility and defect-driven functionality. During synthesis o…
Phonon anomalies and critical scaling in the spin- trimer chain NaCuGeO
P. Srikanth Patnaik, A. K. Bera, Srishti Bhardwaj +4
Low-dimensional quantum magnets provide an ideal platform to explore spin-lattice coupling-mediated quantum correlations, which give rise to emergent quasiparticle excitations. The…
Peculiar Behavior of Optical Polarization in Blazar 1ES 1959+650: Role of Jet Magnetic Field and Geometry
A. Singh, A. Tolamatti, K. K. Singh +2
Measurements of high degree of optical polarization from blazars provide a strong evidence for the optically thin synchrotron radiation from the relativistic leptons in the jet. Th…
Energy-differential measurement of the C(n,p) and C(n,d) reactions at the n_TOF facility at CERN
P. Žugec, N. Colonna, D. Rochman +129
Energy-differential cross section of the C(n,p) and C(n,d) reactions was measured at the neutron time of flight facility n_TOF at CERN. The measur…
