Temperature and terahertz frequency dependence of the dielectric properties of Fe3O4 thin films deposited on Si substrate
Ashish Khandelwal, L. S. Sharath Chandra, Shilpam Sharma +4
The FeO/Si films are considered to be promising materials for THz spintronic applications due to their high temperature magnetic transition and semiconducting properties. I…
Monoclinic symmetry at the nanoscale in lead-free ferroelectric BaZrTiO ceramics
Koushik Dey, Abinash Tripathy, Shikha Rani Sahu +4
Local structural symmetries play a key role in the functionalities of ferroelectric materials and are often found different from average symmetry. Here, we study the real space nan…
Coexistence of local structural heterogeneities and long-range ferroelectricity in Pb-free (1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 ceramics
Koushik Dey, Abdul Ahad, Kamini Gautam +11
Environmentally benign (1-x)Ba(TiZr)O-x(BaCa)TiO (BZT-BCT) ceramics are promising materials due to their remarkable high piezoresponse [Liu…
Temperature induced first order electronic topological transition in -AgSe
L. S. Sharath Chandra, SK. Ramjan, Soma Banik +2
-AgSe is a promising material for room temperature thermoelectric applications and magneto-resistive sensors. However, no attention was paid earlier to the hysteresis in the…
Strain Induced Relaxor-type Ferroelectricity Near Room Temperature in Delafossite CuCrO2
Preeti Pokhriyal, Ashok Bhakar, Parasmani Rajput +5
Polycrystalline samples of CuCrO2 were synthesized by solid state reaction method. Temperature dependent dielectric measurements, synchrotron x-ray diffraction (SXRD), pyroelectric…
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…
