Magneto-dielectric coupling and non-ergodic electrical behaviour in hexagonal Sr0.6Ba0.4MnO3 via local strain driven magnetic ordering
Ritu Rawat, R. J. Choudhary, A. M. Awasthi +6
The crystal structure of hexagonal-Sr0.6Ba0.4MnO3 allows various competing superexchange interactions, leading to intriguing magnetic properties. Local structural changes modify ov…
Interplay of Spin, Lattice, and Charge Degrees of Freedom in Ca3Mn2O7
Pooja Sahlot, A. K. Sinha, A. M. Awasthi
From low-temperature Synchrotron X-ray diffraction, a precise thermal characterization of octahedral distortions in single phase Ruddlesden-Popper Ca3Mn2O7 is performed. Highly sen…
Spin-lattice coupling mediated giant magnetodielectricity across the spin reorientation in Ca2FeCoO5
Gaurav Sharma, Shekhar Tyagi, V. R. Reddy +4
The structural, phonon, magnetic, dielectric, and magneto dielectric responses of the pure bulk Brownmillerite compound Ca2FeCoO5 are reported. This compound showed giant magneto d…
Hexagonal Sr0.6Ba0.4MnO3: Spin and Dipole Coupling via Local Structure
Ritu Rawat, R. J. Choudhary, A. M. Awasthi +5
Hexagonal Sr0.6Ba0.4MnO3 (SBMO) follows P63/mmc symmetry where MnO6 octahedra are both face-shared (Mn2O9 bi-octahedra) and corner-shared via oxygen anion. It undergoes ferroelectr…
