PURPOSE:To prevent the bumping during a vapor deposition process, by providing a material containing a specific level of cobalt, nickel or iron, or an alloy consisting of at least two of these metals and a specific level of silicon. CONSTITUTION:This magnetic material for magnetic recording medium contains one of cobalt, nickel and iron or an alloy consisting of at least two or these metals of 99.5-99.9% by weight and silicon of 0.1-0.5% by weight. The use of such material can prevent the bumping when the melted deposit material is vapor deposited.
