Non-magnetic element substitution effect in Kondo insulator YbB12 and exotic surface effect in this alloy system

Kondo temperature TK’s for Kondo insulator alloys Yb1-xRxB12 (R = Y, Lu, Sc and Zr) show drastic variation as every x increase. It is found that YbB12 in a virtual gap-less state would have a peak at about 25 K in magnetic susceptibility χ(T) from analysis of χ(T) of all these alloys. Up-turns shown...
