Phase Separation in A-site Ordered Perovskite Manganite LaBaMn${}_2$O${}_6$ Probed by ${}^{139}$La and ${}^{55}$Mn NMR

Y. Kawasaki, T. Minami, Y. Kishimoto +5

${}^{139}$La- and ${}^{55}$Mn-NMR spectra demonstrate that the ground state of the A-site ordered perovskite manganite LaBaMn${}_2$O${}_6$ is a spatial mixture of the ferromagnetic (FM) an…
