Novel family of near-room-temperature compensated itinerant pyrochlore ferrimagnets, $R In Co_{4}$ ( $R =$ Dy-Tm)

T. Shiotani, T. Waki, Y. Tabata +2

We successfully synthesized single crystals of a series of C15b Laves phase compounds, $R In Co_{4}$ ( $R =$ Dy-Tm), with Co-pyrochlore and $R$ -fcc sublattices, a…

Non-ergodic Phase Transition in the Global Hysteresis of the Frustrated Magnet DyRu2Si2

S. Yoshimoto, Y. Tabata, T. Waki +1

Some frustrated magnets exhibit a huge hysteresis called "global hysteresis (GH)", where the magnetic plateaus appearing in the increasing field process are skipped in the decreasi…

Unusual strong ferromagnetism in site-ordered cubic Laves phase compound LuInCo $_{4}$ with Co-pyrochlore lattice

Taiki Shiotani, Hiroto Ohta, Takeshi Waki +2

We have successfully synthesized single crystals of the site-ordered cubic (C15b) Laves phase compound LuInCo $_{4}$ with the Co-pyrochlore sublattice for the first time. LuInCo $_{4}$ u…
