Lattice dynamics of topological Dirac semimetal LaAgSb with charge density wave ordering
Ratnadwip Singha, Sudeshna Samanta, Tara Shankar Bhattacharya +5
LaAgSb is a rare material, which offers the opportunity to investigate the complex interplay between charge density wave (CDW) ordering and topology protected electronic band…
Probing lattice dynamics and electron-phonon coupling in topological nodal-line semimetal ZrSiS
Ratnadwip Singha, Sudeshna Samanta, Swastika Chatterjee +6
Topological materials provide an exclusive platform to study the dynamics of relativistic particles in table-top experiments and offer the possibility of wide-scale technological a…
Electrical and magnetic transport study on strain driven ferromagnetic insulating thin film of low doped manganite
Rajib Nath, Sudeshna Samanta, A. K. Raychaudhuri
In this paper we have created a strain driven single crystal like ferromagnetic insulating (FMI) state in a PLD grown thin film of low doped LCMO(X = 0.15)on NGO(100) substrate and…
Growth and physical property study of single nanowire (diameter ~ 45nm) of half doped Manganite
Subarna Datta, Sayan Chandra, Sudeshna Samanta +3
We report here the growth and characterization of functional oxide nanowire of hole doped manganite of La0.5Sr0.5MnO3 (LSMO). We also report four probe electrical resistance measur…
Non-Gaussian resistance noise in the ferromagnetic insulating state of a hole doped manganite
Sudeshna Samanta, A. K. Raychaudhuri, Ya. M. Mukhovskii
We report the observation of a large 1/f noise in the ferromagnetic insulating state (FMI) of a hole doped manganite single crystal of La0.80Ca0.20MnO3 which manifests hopping cond…
Resistance fluctuations and 1/f noise in single crystalline Ni nanowires
Sudeshna Samanta, M. Venkata Kamalakar, A. K. Raychaudhuri
We measured the low frequency (10mHz < f < 10Hz) resistance fluctuations (Noise) in single crystalline ferromagnetic Ni nanowires (diameter ~35nm) in the temperature range 80K-300K…
