Low-dimensional platforms for single photon detection
Pushkar Dasika, Liza Jain, Varun Srivatsav Kondapally +3
A Single-Photon Detector (SPD) can detect extremely low intensity of electromagnetic wave - down to a single photon. Driven by the rapid developments in quantum information science…
Impact of Co2C Nanoparticles on Enhancing the Critical Current Density of Bi-2223 Superconductor
Md. Arif Ali, Sourav M Karan, Nirmal Roy +1
We have investigated the superconducting properties of nanocomposite pellets made from Bi-2223 and Co2C powders. There is loss of superconducting fraction in the nanocomposites, bu…
Coexistence of different pinning mechanisms in Bi-2223 superconductor and its implications for using the material for high current applications
Md. Arif Ali, S. S. Banerjee
We investigate the pinning mechanism in high-critical-current polycrystalline samples of Bi-2223 (Bi2Sr2Ca2Cu3O10) utilized in high current applications. Using differential magneto…
Demonstration of a three-dimensional current mapping technique around a superconductor in a prototype of a conventional superconducting fault current limiter
Md. Arif Ali, S. S. Banerjee
Here we describe a three-dimensional current mapping technology developed for a superconductor using an array of Hall sensors distributed around it. We demonstrate this in a protot…
The Exchange Bias effect in pure Co2C nanoparticles
Nirmal Roy, Md. Arif Ali, Arpita Sen +2
We study the low temperature magnetic properties of nanoparticles of pure transition metal carbide, viz., Co2C, with an average particle diameter of nm. These Co2C nano…
Magneto-optical imaging of stepwise magnetic domain disintegration at characteristic temperatures in EuB_6
Dibya J. Sivananda, Ankit Kumar, Md. Arif Ali +4
Prior to the onset of the ferromagnetic transition in semimetallic EuB_6, unusual magnetic and electric behavior have been reported. Using a highly sensitive magneto-optical imagin…
