The prototype high-entropy oxide (HEO) Y0.2La0.2Ce0.2Pr0.2Sm0.2O2−δ represents a particularly complex class of HEOs with significant anion sublattice entropy. system takes either fluorite or bixbyite-type crystal structure, depending on synthesis kinetics and thermal history. Here, we synthesize bulk ceramics epitaxial thin films use diffraction to explore symmetry phase. Thin exhibit the high phase, while adopt lower bixbyite difference in chemical ordering observed between vapor-deposited...
Dirac and Weyl semimetals are a central topic of contemporary condensed matter physics, the discovery new compounds with Dirac/Weyl electronic states is crucial to advancement topological materials quantum technologies. Here we show widely applicable strategy that uses high configuration entropy engineer relativistic states. We take AMnSb
How disorder affects magnetic ordering is always an intriguing question, and it becomes even more interesting in the recently rising high entropy oxides due to extremely density. However, lack of high-quality single crystal samples, strong compositional effect on transition has not been deeply investigated. In this work, we have successfully synthesized crystalline spinel ferrites (Mg
This manuscript presents a working model linking chemical disorder and transport properties in correlated-electron perovskites with high-entropy formulations framework to actively design them. We demonstrate this new learning epitaxial Sr$x$(Ti,Cr,Nb,Mo,W)O$3$ thin films that exhibit exceptional crystalline fidelity despite diverse formulation where most B-site species are highly misfit respect valence radius. X-ray diffraction, photoelectron spectroscopy, transmission electron microscopy...
Multiferroic materials host both ferroelectricity and magnetism, offering potential for magnetic memory spin transistor applications. Here, we report a multiferroic chalcogenide semiconductor Cu 1−x Mn 1+y SiTe 3 (0.04 ≤ x 0.26; 0.03 y 0.15), which crystallizes in polar monoclinic structure ( Pm space group). It exhibits canted antiferromagnetic state below 35 kelvin, with hysteresis remanent magnetization under 15 kelvin. We demonstrate multiferroicity strong magnetoelectric coupling...
Abstract High entropy oxides (HEOs) have garnered much interest due to their available high degree of tunability. Here, we study the local structure (MgNiCuCoZn) 0.167 (MnCr) 0.083 O, a composition based on parent HEO 0.2 O. We synthesized series thin films via pulsed laser deposition at incremental oxygen partial pressures. X‐ray diffraction shows lattice parameters decrease with increased pO 2 pressures until onset phase separation. absorption fine that specific atomic species in dictate...
