Effect of Co substitution on the magnetic properties of BiFeO3
TL;DR: In this article, a model based on the existing spinoidal cyclic arrangement of spins is proposed to explain the observed data, and a very dilute concentration of Co þ 3 in BiFeO3 is found sufficient to tailor the magnetic properties.
Journal ArticleDOI
Quenching of photoconductivity in Fe doped CdS thin films prepared by spray pyrolysis technique
Nitu Badera,Bhavana Godbole,S.B. Srivastava,P. N. Vishwakarma,L. S. Sharath Chandra,Deepti Jain,Mohan Gangrade,T. Shripathi,Vasant Sathe,V. Ganesan +9 more
TL;DR: In this paper, the X-ray diffraction peaks position of Cd1−xFexS shifts to higher angle with increasing Fe concentration indicating decrease in cell volume, and temperature dependence of resistivity follows Arrhenius behavior having lower activation energy with increasingFe concentration in dark while there is a little variation in light.
Journal ArticleDOI
Rollable Magnetoelectric Energy Harvester as a Wireless IoT Sensor
Sujoy Kumar Ghosh,Krittish Roy,Hari Krishna Mishra,M. R. Sahoo,Biswajit Mahanty,Biswajit Mahanty,P. N. Vishwakarma,Dipankar Mandal +7 more
TL;DR: In this paper, a flexible and rollable magneto-mechano-elec... is proposed to deal with parasitic magnetic noise arising from an electrical power transmission system, which is the most abundant form of waste energy in our daily life.
Journal ArticleDOI
Synthesis of multi-wall carbon nanotubes by simple pyrolysis
Pitamber Mahanandia,P. N. Vishwakarma,Karuna Kar Nanda,V. Prasad,K. Barai,A.K. Mondal,Sachindra Nath Sarangi,G.K. Dey,S.V. Subramanyam +8 more
TL;DR: In this article, a pyrolysis technique was developed for the synthesis of multi-walled carbon nanotubes (MWCNTs) using reaction quartz tube without using carrier gas.
Journal ArticleDOI
