With a sample of about 227 million BB pairs recorded with the BABAR detector at the PEP-II storage ring we perform a full angular analysis of the decay B0->PhiK*0(892). We measure the branching fraction to be (9.2+-0.9+-0.5)10^-6 and determine the fractions of longitudinal and parity-odd transverse contributions as f_L=0.52+-0.05+-0.02 and f_perp=0.22+-0.05+-0.02, respectively. The phases of the parity-even and parity-odd transverse amplitudes relative to the longitudinal amplitude are found to
