Emergent Intrinsic Ferromagnetism in Two-Dimensional Trigonal Rhodium Oxide
Two-dimensional (2D) van der Waals single crystals with
long-range
magnetic order are the precondition and urgent task for developing
a 2D spintronics device. In contrast to graphene and transition metal
dichalcogenides, the study of 2D single-crystal metal oxides with
intrinsic ferromagnetic properties remains a huge challenge. Here,
we report a large-size trigonal single-crystal rhodium oxide (SC-Tri-RhO2), with crystal parameters of a = b = 3.074 Ã…, c = 6.116 Ã…, and
a space group of P3Ì…m1 (164),
exhibiting strong ferromagnetism (FM) at a rather high temperature.
Furthermore, theoretical calculations suggest that the ferromagnetism
in SC-Tri-RhO2 originates from spin splitting near the
Fermi level, and the total magnetic moment is contributed mainly by
the Rh atom
