Here, we report the catalytic degradation of organic compounds by exploiting the magnetoelectric (ME) nature of cobalt ferrite-bismuth ferrite (CFO-BFO) core-shell nanoparticles. The combination of magnetostrictive CFO with the multiferroic BFO gives

The instability of ferroelectric ordering in ultra-thin films is one of the most important fundamental issues pertaining realization of a number of electronic devices with enhanced functionality, such as ferroelectric and multiferroic tunnel junction

Layered iridates have been the subject of intense scrutiny on account of their unusually strong spin-orbit coupling, which opens up a narrow gap in a material that would otherwise be a metal. This insulating state is very sensitive to external pertur

Possible Scale Invariant Linear Magnetoresistance in Pyrochlore Iridates Bi$_2$Ir$_2$O$_7$

Autor: Chu, Jiun-Haw, Liu, Jian, Zhang, Han, Noordhoek, Kyle, Riggs, Scott. C., Shapiro, Maxwell, Serero, Claudy Ryan, Yi, Di, Melissa, M., Suresha, S. J., Frontera, C., Arenholz, E., Vishwanath, Ashvin, Marti, Xavi, Fisher, I. R., Ramesh, R.

Publikováno v: New J. Phys. 21 113041 (2019)

We report the observation of a linear magnetoresistance in single crystals and epitaxial thin films of the pyrochlore iridate Bi$_2$Ir$_2$O$_7$. The linear magnetoresistance is positive and isotropic at low temperatures, without any sign of saturatio
