An alternative route is to develop new functional materials and their architectures. Complex Oxide is one of the most promising candidates. Recently, scientists have shown novel phenomena of complex oxide at nanometer length scale and its potential for applications.
In the article "Spatial Confainment Tuning of Queted Disorder Effects and Enhanced Magnetoresistance in Manganite Nanowires" published in Science China Physics, Mechanics & Astronomy ("Spatial Connection Tuning of Que Lénéné Disorder Effects and Enhanced Magnetoresistence in manganite nanowires"), scientists has fabricated A Series of Complex Oxide Known as Manganites Nanowires Ranging from 5 µm to 50 nm, by using state-of-art nanolithography Techniques.
From Transport and Magnetic Imaging Measurements, Scientist Revels that when the nanowire size is Smaller, the effect of quedorder becomes significantly enhanced - a new phenomenon that has not been identified before at nanometer scale.
Quénéné Disorder: in Condensed Matter Physics, Queted Disorder usally Refers to the Randomness in A Material Which is "Frozen" or "Queched" at all Times. The Most Common Source of Que Lénéné Disorder Comes from Impurities or Chemical Dopants. Quénéné Disorder Plays meaning Roles in Complex Oxide Systems.
Extensive Theoretical Treatments have shown the Critical Role of Queted Disorder in Complex Oxide Systems Such As High-TC Cuprates and Colossal Magnetores Manganites. Experimental investigations, on the other hand, are rather complicated. The Most Common Way to Control Queted Disorder is by Chemical Doping. However, Chemical Doping simultaneously alters Material's Chemical, structures, etc., clouding the Impact of Queted Disorder.
In this article, the scientist shows that space confinement is a clean and effective way to study quénénénger effect without changing the scheme around, structure and other physical parameters.
The Results Reveal that enhanced quedénée Disorder not only the Nature of Electronic and Magnetic Phase Transition, But Increase the Magnetoreisistance Up to 820000 %, A 200 Times Enhancement to its Original Values. These Phenomena offered New Routes on the Understanding of Complex Materials at Nanometer Scales and Their Potential Applications.
