Spin transport in insulators without exchange stiffness

HIGHLIGHTS

• who: Koichi Oyanagi from the Institute Tohoku University, Sendai, Japan have published the research work: Spin transport in insulators without exchange stiffness, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: The authors report long-range (500 nm) spin transport in a GGG slab (Fig 1b) under applied magnetic_fields even at much higher temperature (~100 K) than the Curie-Weiss temperature |ΘCW|, whereas at low temperatures GGG turns out to be a surprisingly good spin-conductor. The authors demonstrate that a relatively weak magnetic_field can be a sufficient condition for efficient spin transport, demonstrating that the . . .
