【 摘 要 】

Motivated by recent reports [Luders et al., Phys. Rev. B 80, 241102 (2009)] of room-temperature ferromagnetism in vanadium oxide based superlattices, a single-site dynamical mean-field study of the dependence of the paramagnetic-ferromagnetic phase boundary on superlattice geometry was performed. An examination of variants of the experimentally determined crystal structure indicate that ferromagnetism is found only in a small and probably inaccessible region of the phase diagram. Design criteria for increasing the range over which ferromagnetism might exist are proposed.
