Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

Advanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Magnetoelectric domain engineering from micrometer to Ångstrøm scales

Physical Review Research
The functionality of magnetoelectric multiferroics depends on the formation, size, and coupling of their magnetic and electric domains. Knowing the parameters guiding these criteria is a key effort in the emerging field of magnetoelectric domain ...

Some current problems in perovskite nano-ferroelectrics and multiferroics: kinetically-limited systems of finite lateral size

Science and Technology of Advanced Materials, 2015
We describe some unsolved problems of current interest; these involve quantum critical points in ferroelectrics and problems which are not amenable to the usual density functional theory, nor to classical Landau free energy approaches (they are ...

Electric‐Field‐Driven Reversal of Ferromagnetism in (110)‐Oriented, Single Phase, Multiferroic Co‐Substituted BiFeO3 Thin Films

Advanced Materials, EarlyView.
Electric‐field‐induced magnetization reversal is a long‐sought‐after achievement in materials engineering for use in next‐generation, ultra‐low power consumption memory devices. This work demonstrates fully electric‐field‐driven switching of the out‐of‐plane component of magnetization in (110)‐oriented Co‐substituted BiFeO3 thin films at room ...

Using ultrashort optical pulses to couple ferroelectric and ferromagnetic order in an oxide heterostructure

, 2014
A new approach to all-optical detection and control of the coupling between electric and magnetic order on ultrafast timescales is achieved using time-resolved second harmonic generation (SHG) to study a ferroelectric (FE)/ferromagnet (FM) oxide ...

Translation domains in multiferroics [PDF]

arXiv, 2010
Translation domains differing in the phase but not in the orientation of the corresponding order parameter are resolved in two types of multiferroics. Hexagonal (h-) YMnO$_3$ is a split-order-parameter multiferroic in which commensurate ferroelectric translation domains are resolved by piezoresponse force microscopy whereas MnWO$_4$ is a joint-order ...

Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites

Advanced Materials, EarlyView.
Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Unconventional Ferroelectric Switching via Local Domain Wall Motion in Multiferroic ε‐Fe2O3 Films

Advanced Electronic Materials, 2020
Deterministic polarization reversal in ferroelectric and multiferroic films is critical for their exploitation in nanoelectronic devices. While ferroelectricity has been studied for nearly a century, major discrepancies in the reported values of coercive
