  The magneto-transport and magnetization measurements of Sb1.90Cu0.10Te3 were
performed at different temperatures and different fields. Magneto-transport
measurement at high field indicates the coexistence of both bulk and surface
states. The magnetization shows the induced antiferromagnetic ordering with Cu
doping and the observed quantum oscillation in it indicates that magnetization
in Sb1.90Cu0.10Te3 is the bulk property. The non linearity in Hall data
suggests the existence of anomalous and topological Hall effect. The anomalous
and topological Hall effect (THE) from measured hall data of Cu doped Sb2Te3
topological insulator have been evaluated.
