Interface engineering of the anomalous Hall effect in Ni-based heterostructures
Mainak Ghosh, Kusampal Yadav, Kalyan sarkar +3
Using a combined experimental and first-principles theoretical approach, we demonstrate interface engineering of the anomalous Hall effect in Ni-based epitaxial thin-film heterostr…
Enhanced negative capacitance in La-doped Pb(ZrTi)O ferroelectric capacitor from tuning of bias voltage pulse
Ganga S. Kumar, Sudipta Goswami, Subhashree Chatterjee +5
We report a remarkable bias voltage dependent specific negative capacitance in multidomain La-doped Pb(ZrTi)O (PLZT) ferroelectric capacitors. The specific nega…
Giant topological Hall effect in epitaxial NiFe/LaSrMnO thin film heterostructures
Kusampal Yadav, Dilruba Hasina, Nasiruddin Mondal +2
The emergence of new physical properties at the interfaces between complex oxides has always been of both fundamental and practical importance. Here, we report the observation of a…
Evidence of spin reorientation transition below 150 K from magnetic force microscopy in a ferromagnetic BiFeO thin film
Sudipta Goswami, Shubhankar Mishra, Kishor Kumar Sahoo +8
We investigated the magnetic transitions in BiFeO at low temperature (5-300 K) and observed nearly 90 rotation of magnetic domains (imaged by vertical magnetic force micros…
