Excited states of have been investigated by in-beam 
-ray spectroscopic techniques using the 
(
, 
) reaction at a beam energy of 46 MeV. The level scheme of is significantly extended with the addition of more than 20 new transitions. For the positive-parity yrast band, it is extended to 
state and 
higher than the earlier work. A negative-parity band decaying to the yrast band by eleven new linking transitions is identified, and several E2 crossover transitions of this band are observed, thereby confirming the spin-parity assignment and the ordering of dipole transitions above the 
level. Experimental total angular momenta, kinematical and dynamical moments of inertia, and B(M1)/B(E2) ratio for the negative-parity band are compared with the predictions of self-consistent titled axis cranking relativistic mean-field model. Based on the theoretical description and the observed characteristics, the negative-parity dipole band is suggested as a magnetic rotational band arising from shears mechanism.
