Spin-lattice Coupling and Magneto-dielectricity in Ca3Mn2O7 Layered Perovskite
Pooja Sahlot, Gaurav Sharma, Vasant Sathe +1
Dielectric study on Ca3Mn2O7 features relaxor-like segmented dynamics below the antiferromagnetic ordering. Dipolar relaxations of different origin are spectrally resolved exhibiti…
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…
Bipolar electrocaloric effect in Pb1-xGdx(Mg1+x/3Nb2-x/3)O3 ceramic: relaxor with super-dipolar glass state
Adityanarayan H. Pandey, A. M. Awasthi, Surya Mohan Gupta
The electrocaloric (EC) effect is calculated for Gd-substituted PMN (x = 0 to 0.1) relaxors from temperature dependent heat capacity and polarization measurements, using a thermody…
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…
