Abstract: We report a computational discovery of novel grain boundary structures and multiple grain boundary phases in elemental body-centered cubic (bcc) metals represented by tungsten, tantalum and molybdenum. While grain boundary structures created by the γ-surface… read more here.

Abstract: We study the evolution of helical magnetism in MnGe chiral magnet upon partial substitution of Mn for 3$d$-Co and 4$d$-Rh ions. At high doping levels, we observe spin helices with very long periods—more than ten… read more here.

DOI: 10.1103/physrevlett.128.035701
Abstract: We derive a theory that describes homogeneous nucleation of grain boundary (GB) phases. Our analysis takes account of the energy resulting from the GB phase junction, the line defect separating two different GB structures, which… read more here.
