Enhanced negative capacitance in La-doped Pb(ZrTi)O ferroelectric capacitor from tuning of bias voltage pulse
Ganga S. Kumar, Sudipta Goswami, Subhashree Chatterjee +5
We report a remarkable bias voltage dependent specific negative capacitance in multidomain La-doped Pb(ZrTi)O (PLZT) ferroelectric capacitors. The specific nega…
Evidence of spin reorientation transition below 150 K from magnetic force microscopy in a ferromagnetic BiFeO thin film
Sudipta Goswami, Shubhankar Mishra, Kishor Kumar Sahoo +8
We investigated the magnetic transitions in BiFeO at low temperature (5-300 K) and observed nearly 90 rotation of magnetic domains (imaged by vertical magnetic force micros…
Charge-transfer-driven enhanced room-temperature ferromagnetism in BiFeO/Ag nanocomposite
Tania Chatterjee, Shubhankar Mishra, Arnab Mukherjee +3
We report observation of more than an order of magnitude jump in saturation magnetization in BiFeO/Ag nanocomposite at room temperature compared to what is observed in bare BiF…
Room-temperature multiferroicity in GaFeO thin film grown on (100)Si substrate
Sudipta Goswami, Shubhankar Mishra, Kausik Dana +7
Room-temperature magnetoelectric multiferroicity has been observed in c-axis oriented GaFeO thin films (space group ), grown on economic and technologically important (…
Room-temperature surface multiferroicity in YNiMnO nanorods
Shubhankar Mishra, Amritendu Roy, Aditi Sahoo +5
We report observation of surface-defect-induced room temperature multiferroicity - surface ferromagnetism ( at 50 kOe 0.005 emu/g), ferroelectricity ( 2 nC/cm…
High-resolution surface structure determination from bulk X-ray diffraction data
Nirman Chakraborty, Swastik Mondal
The key to most surface phenomenon lies with the surface structure. Particularly it is the charge density distribution over surface that primarily controls overall interaction of t…
