TL;DR: In this paper, the authors studied the magnetic properties of perovskite and found that the holes introduced by Sr doping are attracted to the ions where they stabilize to lowest temperatures an intermediate-spin state at neighboring trivalent cobalt.

TL;DR: In this article, it was shown that not all the title perovskites exhibit a first-order transition at their Curie temperatures, while all the second-order ones do.

TL;DR: In this article, a method based on a micro-emulsion route is presented to obtain magnetic nanoparticles of different sizes, offering several advantages with respect to other similar methods, including the ability to obtain defined X-ray diffraction patterns without the complications of working in an inert atmosphere or with extra amounts of Fe2+, thereby eliminating the need for further steps in order to achieve good crystallization of the material.

TL;DR: The data are consistent with an inverse-DM mechanism for multiferroic behavior, as the electric polarization exhibits an unusual memory effect, as it remembers the direction of the previous two magnetic-field pulses applied.

TL;DR: In this article, the influence of the synthetic conditions (temperature, time of synthesis and nature of solvent) on the quality of the obtained ferrites and on their particle size was studied.
