Abstract
We examined the magnetic properties of YbBe13, which exhibits an antiferromagnetic order below TN = 1.2 K. Unlike other MBe13 compounds (M = rare earth/actinide elements), based on elastic neutron scattering, we observed an incommensurate magnetic propagation vector τ = (0,0,τz), where τz = 0.5385 is in the reciprocal lattice unit. Additionally, we constructed a precise magnetic phase diagram for YbBe13. We observed non-trivial magnetic anomalies in YbBe13, which cannot be understood based on a simple helical order. Our results for YbBe13 provide an opportunity to reconsider the electron state of UBe13 and present an important step toward a comprehensive understanding of magnetic correlations in MBe13 series.
