Nanoscale phase separation in manganites

, 2003
We study the possibility of nanoscale phase separation in manganites in the framework of the double exchange model. The homogeneous canted state of this model is proved to be unstable toward the formation of small ferromagnetic droplets inside an ...

Electronically soft phases in manganites [PDF]

Nature, 2005
The phenomenon of colossal magnetoresistance in manganites is generally agreed to be a result of competition between crystal phases with different electronic, magnetic and structural order; a competition which can be strong enough to cause phase separation between metallic ferromagnetic and insulating charge-modulated states.

Investigating the Iron‐Steam Process for Coupling With SOEC and SOFC: A Step Toward Integrated Hydrogen and Electricity Storage

steel research international, EarlyView.
Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Preparation of high crystalline nanoparticles of rare-earth based complex pervoskites and comparison of their structural and magnetic properties with bulk counterparts

, 2017
A simple route to prepare Gd$_{0.7}$Sr$_{0.3}$MnO$_3$ nanoparticles by ultrasonication of their bulk powder materials is presented in this article. For comparison, Gd$_{0.7}$Sr$_{0.3}$MnO$_3$ nanoparticles are also prepared by ball milling.

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

Advanced Materials, Volume 38, Issue 26, 8 May 2026.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).
