Phase evolution and enhanced room temperature piezoelectric properties response of lead-free Ru doped BaTiO3 ceramic
Kumar Brajesh, Sudhir Ranjan, Ashish Garg
Recent years have witnessed considerable work on the development of lead-free piezoelectric ceramic materials and their structure-property correlations. The development of piezo re…
Room Temperature Structural, Magnetic and Dielectric Characteristics of La Doped CuO Bulk Multiferroic
Kumar Brajesh, Sudhir Ranjan, Rajeev Gupta +2
In this manuscript, we report room temperature structural, microstructural, optical, dielectric, and magnetic properties of CuO and Cu0.995La0.005 ceramics, synthesized by solid-st…
Low temperature magnetic and dielectric properties correlation in Fe-doped copper (ii) oxide ceramics for potential device application
Kumar Brajesh, Ritamay Bhunia, Shashikant Gupta +3
The bulk samples of CuO and Fe-doped CuO were synthesized by ceramics methods. Structural and compositional analyses were performed by using X-ray diffraction, SEM, and EDAX. Throu…
Fluidisation of yield stress fluids under vibration
A. Garg, N. Bergemann, B. Smith +2
Motivated by the industrial processing of chocolate, we study experimentally the fluidisation of a sessile drop of yield-stress fluid on a pre-existing layer of the same fluid unde…
Evidence for Incipient Ferroelectricity in YCrO3
Ashish Kumar Mall, Barnita Paul, Ashish Garg +1
Cubic structure is one of the most commonly found structures for oxides at high temperature. As the temperature is lowered only a handful of these oxides exhibit ferroelectricity w…
Origin of Ferroelectricity in Orthorhombic LuFeO
Ujjal Chowdhury, Sudipta Goswami, Amritendu Roy +13
We demonstrate that small but finite ferroelectric polarization (0.01 C/cm) emerges in orthorhombic LuFeO () at (600 K) because of commensurate (…
