Journal ArticleDOI
Anomalous transport and magnetic behaviours of the quaternary Heusler compounds CoFeTiSn and CoFeVGa
Snehashish Chatterjee,Subarna Das,S. Pramanick,Surjani Chatterjee,Saurav Giri,Aritra Banerjee,Subham Majumdar +6 more
TL;DR: In this article, the electrical transport and magnetic properties of the newly synthesized quaternary Heusler compounds CoFeTiSn and CoFeVGa were investigated and it was shown that the system exhibits an activated semiconducting behavior in the paramagnetic phase, it turns abruptly to a metallic phase with the onset of ferromagnetic transition.
Journal ArticleDOI
Thermoelectric materials taking advantage of spin entropy: lessons from chalcogenides and oxides
Sylvie Hébert,Ramzy Daou,Antoine Maignan,Subarna Das,Aritra Banerjee,Yannick Klein,Cédric Bourgès,Naohito Tsujii,Takao Mori,Takao Mori +9 more
TL;DR: The interplay between charges and spins may influence the dynamics of the carriers and determine their thermoelectric properties as mentioned in this paper, and in that respect, magneto-thermoelectoric power MTEP, i.e. the measur...
Journal ArticleDOI
Evolution of phonon anharmonicity in Se-doped S b 2 T e 3 thermoelectrics
Diptasikha Das,Subarna Das,P. Singha,K. Malik,A. K. Deb,Arpan Bhattacharyya,V. A. Kulbachinskii,Raktima Basu,Sandip Dhara,Samir Kumar Bandyopadhyay,Aritra Banerjee +10 more
TL;DR: In this article, the phonon anharmonicity in Se-doped polycrystalline polygonal systems was investigated using temperature-dependent synchrotron powder diffraction, Raman spectroscopic studies, and heat capacity measurements.
Journal ArticleDOI
Mn doping-induced structural and magnetic transformations in the antiferroelectric phase of the Bi1−xNdxFeO3 perovskites
V. A. Khomchenko,I. O. Troyanchuk,Teresa M. R. Maria,Dmitry V. Karpinsky,Subarna Das,Vitor S. Amaral,José A. Paixão +6 more
TL;DR: In this article, the effect of Mn doping on the crystal structure and magnetic properties of the intermediate antiferroelectric and weak ferromagnetic phase of the Bi1−xNdxFeO3 perovskites was investigated.
Journal ArticleDOI
Role of graphite on the thermoelectric performance of Sb2Te3/graphite nanocomposite
Subarna Das,P. Singha,A. K. Deb,Sidhartha Das,Surjani Chatterjee,V. A. Kulbachinskii,Vladimir G. Kytin,D. A. Zinoviev,N. V. Maslov,Sandip Dhara,Samir Kumar Bandyopadhyay,Aritra Banerjee +11 more
TL;DR: In this paper, the contribution of graphite to heat transport mechanism is addressed both experimentally and theoretically and a low κL value of 0.8 Wm−1 1 K−1 K−K−1 is reported, which mostly arises due to enhanced phonon scattering at the heterointerfaces created by the addition of graphites.
