Query: Large Magnetoresistance and Weak Antilocalization in V1-delta Sb2 Single
  Crystal   The binary pnictide semimetals have attracted considerable attention due to
their fantastic physical properties that include topological effects, negative
magnetoresistance, Weyl fermions and large non-saturation magnetoresistance. In
this paper, we have successfully grown the high-quality V1-deltaSb2 single
crystals by Sb flux method and investigated their electronic transport
properties. A large positive magnetoresistance that reaches 477% under a
magnetic field of 12 T at T = 1.8 K was observed. Notably, the
magnetoresistance showed a cusp-like feature at the low magnetic fields and
such feature weakened gradually as the temperature increased, which indicated
the presence of weak antilocalization effect (WAL). The angle-dependent
magnetoconductance and the ultra-large prefactor alpha extracted from the
Hikami-Larkin-Nagaoka equation revealed that the WAL effect is a 3D bulk effect
originated from the three-dimensional bulk spin-orbital coupling.
