Temperature-Sensitive Magnetic Film for a Magneto-optic Memory

Abstract
Thin cobalt films, with low phosphorous content, electroplated on suitable substrates, at a pH of 6–6.5, have useful properties for thermomagnetic recording. They have a room‐temperature coercivity, Hc(25°C) in excess of 200 Oe, Hc(25°C)/Hc(150°C) in excess of 3, and good working margins.
