Disconnection-Mediated Twin/Twin-Junction Migration in FCC metals
Mingjie Xu, Kongtao Chen, Fan Cao +7
We present the results of novel, time-resolved, in situ HRTEM observations, molecular dynamics (MD) simulations, and disconnection theory that elucidate the mechanism by which the…
Magneto-electric Tuning of Pinning-Type Permanent Magnets through Atomic-Scale Engineering of Grain Boundaries
Xinglong Ye, Fengkai Yan, Lukas Schaefer +11
Pinning-type magnets maintaining high coercivity, i.e. the ability to sustain magnetization, at high temperature are at the core of thriving clean-energy technologies. Among these,…
Role of intermediate 4 states in tuning the band structure of high entropy oxides
Abhishek Sarkar, Benedikt Eggert, Leonardo Velasco +8
High entropy oxides (HEOs) are single phase solid solutions consisting of 5 or more cations in approximately equiatomic proportions. In this study, we show reversible control of op…
Magnetic properties of rare earth and transition metal based perovskite type high entropy oxides
Ralf Witte, Abhishek Sarkar, Leonardo Velasco +7
High entropy oxides (HEO) are a recently introduced class of oxide materials, which are characterized by a large number of elements (i.e. five or more) sharing one lattice site whi…
Epitaxial strain adaption in chemically disordered FeRh thin films
Ralf Witte, Robert Kruk, Di Wang +5
Strain and strain adaption mechanisms in modern functional materials are of crucial importance for their performance. Understanding these mechanisms will advance innovative approac…
High entropy oxides: An emerging prospect for magnetic rare earth - transition metal perovskites
Ralf Witte, Abhishek Sarkar, Robert Kruk +4
It has been shown that oxide ceramics containing multiple transition and/or rare-earth elements in equimolar ratios have a strong tendency to crystallize in simple single phase str…
