Time resolved eye diagrams to exploit hidden high energy branches in a nonlinear wideband vibration energy harvester

Kankana Paul, Saibal Roy, Andreas Amann

A wideband vibration energy harvester with multiple nonlinear forces is investigated. The nonlinearities are due to repulsive magnets and hardening springs, which gives rise to mul…

Reply to the Comment on "Superspin Glass Mediated Giant Spontaneous Exchange Bias in BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$ Nanocomposite [Phys. Rev. Lett. 110, 107201 (2013)]"

Tuhin Maity, Sudipta Goswami, Dipten Bhattacharya +1

In this article we reply to the concerns raised by Harres $et al$ . [Phys. Rev. Lett. (to be published)] about some of the results reported in our original paper [T. Maity…

Large magnetoelectric coupling in nanoscale BiFeO $_{3}$ from direct electrical measurements

Sudipta Goswami, Dipten Bhattacharya, Lynette Keeney +9

We report the results of direct measurement of remanent hysteresis loops on nanochains of BiFeO $_{3}$ at room temperature under zero and $\sim$ 20 kOe magnetic field. We noticed a sup…

Origin of the asymmetric exchange bias in BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$ nanocomposite

Tuhin Maity, Sudipta Goswami, Dipten Bhattacharya +1

We show from detailed magnetometry across 2-300 K that the BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$ nanocomposite offers a unique spin morphology where superspin glass (SSG) and dilute antiferr…

Spontaneous exchange bias in a nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$

Tuhin Maity, Sudipta Goswami, Dipten Bhattacharya +2

We have observed a large as well as path-dependent spontaneous exchange bias (H $_{S E B}$ ) ( $\sim$ 30-60 mT) in a nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$ across 5-300 K when it i…

Superspin Glass Mediated Giant Spontaneous Exchange Bias in a Nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$

Tuhin Maity, Sudipta Goswami, Dipten Bhattacharya +1

We observe an enormous $spontaneous$ exchange bias ( $\sim$ 300-600 Oe) - measured in an unmagnetized state following zero-field cooling - in a nanocomposite of BiFeO $_{3}$ ($…
