Successive magnetic phase transitions with magnetoelastic and magnetodielectric coupling in the ordered triple perovskite SrCaRuO
Arun Kumar, Pascal Manuel, Sunil Nair
We report a comprehensive temperature-dependent investigation of the 1:2 ordered triple perovskite system SrCaRuO. It crystallizes in the monoclinic structure with spac…
Evidence for superferrimagnetic clusters and spin-glass transition involving 4f Dy3+ spins in h-DyMnO3: A new twist to 4f Re3+ spin ordering in hexagonal manganites
P. Aravinth Kumar, Arun Kumar, Keshav Kumar +5
The ferroelectric phase of the multiferroic hexagonal manganites (h-ReMnO3) has been reported to undergo a series of magnetic transitions involving long-range ordering/reorientatio…
Evidence for two spin-glass transitions with magnetoelastic and magnetoelectric couplings in the multiferroic (BiBa)(FeTi)O system
Arun Kumar, S. D. Kaushik, V. Siruguri +1
For disordered Heisenberg systems with small single ion anisotropy, two spin glass transitions below the long range ordered phase transition temperature has been predicted theoreti…
The Ground state of BiFeO3: Low temperature magnetic phase transitions revisited
Arun Kumar, Dhananjai Pandey
Recent neutron diffraction and NMR studies suggest that the incommensurately modulated spin cycloid structure of BiFeO3 is stable down to 4.2 K, whereas DC [M(T)] and AC [\c{hi} (ω…
