DOI: 10.1103/physrevb.96.020413
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: 10.3390/fluids3020026
Abstract: Topological defects are important in determining the properties of physical systems and are known varyingly depending on the broken symmetry. In superfluid helium, they are called vortices; in periodic crystals, one refers to dislocations; and… read more here.
