The effect of a CoO underlayer on Co-O films deposited obliquely is investigated through magnetic measurements and micro structure observations of the films. The under-layer makes the coercivity of the films high. Films with the underlayer have high uniaxial magnetic anisotropy along columnar grains, becauseof the c-axis preferred orientation of hcp-Co. The granular texture of the underlayer promotes separation between columnar grains growing obliquely.
