Abstract

We have performed scanning photoemission spectromicroscopy of BaV 10 O 15 across the metal-insulator transition at 123 K, which is accompanied by V 3d charge/orbital order and V trimerization. Nucleation of metallic domains is observed at the cleaved surface of BaV 10 O 15 single crystals, similar to Cr-doped V 2 O 3 in which electronic configurations of Cr 3+ and V 3+ are the same as those of V 2+ and V 3+ in BaV 10 O 15 . Typical domain size is ~5-10 μm at 150 K, just above the transition temperature. The metallic domains continuously grow up to 240 K, well above the transition temperature. The temperature evolution of the metallic phase in BaV 10 O 15 is different from that of Cr-doped V 2 O 3 , probably due to the charge degrees of freedom in BaV 10 O 15
