High‐Throughput Screening Methods
In article number 2204520, Lydia Helena Wong and co‐workers discover an efficient ternary Mn‐based spinel oxide (Fe0.3Co1.2Mn1.5O4) for oxygen evolution reaction (OER) by employing high‐throughput screening methods. The high OER catalytic performance originates from the multiple active sites in various geometric sites, i.e., Co2+ in tetrahedral‐ and Mn3+ in octahedral‐...
The discovery of more efficient and stable catalysts for oxygen evolution reaction (OER) is vital in improving the efficiency of renewable energy generation devices. Given the large numbers of possible binary and ternary metal oxide OER catalysts, high‐throughput methods are necessary to accelerate the rate of discovery. Herein, Mn‐based spinel oxide, Fe10Co40Mn50O, is identified for the first time...
In aticle number 2004683, Ariando Ariando and co‐workers report that topological Hall effect is found in a CaMnO3/CaIrO3/CaMnO3//LaAlO3(001) heterostructure, which indicates the presence of magnetic Skyrmions entailing the charge‐transfer induced magnetic superexchange. Thickness variations and atomic structure analyses suggest that the Dzyaloshinskii–Moriya interaction originates from the top CaMnO...
Exploring exotic interface magnetism due to charge transfer and strong spin‐orbit coupling has profound application in the future development of spintronic memory. Here, the emergence and tuning of topological Hall effect (THE) from a CaMnO3/CaIrO3/CaMnO3 trilayer structure are studied in detail, which suggests the presence of magnetic Skyrmion‐like bubbles. First, by tilting the magnetic field direction,...
