High magnetic fields up to 105 T have been utilized in deriving the upper
critical field Bc2β of LaFeAsO1βxβHxβ throughout whole
temperatures below Tcβ. Resistivity measurements demonstrate that
Bc2β behaves differently in samples with x=0.12 (SC1) from those
with 0.32 (SC2). In SC1, the two-band model assuming the s-wave pairing gives
a good fitting with repulsive intraband interaction and dominant interband
coupling. In SC2, we have to assume attractive intraband interaction with weak
interband coupling, which in fact suggests a non-s-wave pairing in view of
the strong Coulomb repulsion. These results support the possibility that SC1
and SC2 have different pairing symmetries
