  The 4f^6 systems were hypothesized to possess non-magnetic (J = 0) ground
state. However, all such systems have distinctly shown the presence of non-zero
effective moment. In this context, a rare earth orthovanadate EuVO4, which in
spite of having J = 0 ground state, possess non-zero magnetic moment. Our
studies reveal three different regions in this compound, boundaries of which
are demarcated from susceptibility data. The high temperature susceptibility
exhibits linear dependence on temperature which arises due to tetragonal
crystal field, followed by a temperature independent plateau like region,
ascribed to Van Vleck paramagnetism. At low temperatures, Curie-Weiss like
behaviour is observed, which arise due to magnetic Eu2+ moments and results in
non-zero effective moment. Our analysis reveals that the separation ({\lambda})
between the J = 0 and J = 1 states decreases on increasing the external
magnetic field which leads to an enhanced effective moment at higher fields.
