The authors describe a new type of sputtering apparatus which can form a stable toroidal plasma developed in order to deposit magnetic films with a homogeneous and dense structure and excellent properties under the conditions of low argon gas pressure, low applied voltage and low substrate temperature around 30 {sup 0}C. All Co-Cr films deposited by this apparatus were composed of hcp phase crystallites with c-axis orientation {Delta}{theta}/sub 50/ ranging from 8 to 13{sup 0}. The saturation magnetization Ms varied from 380 to 780 emu/cc and perpendicular coercivity Hc varied from 100 to 300 Oe.
