Abstract
There are provided a soft magnetic material having a high saturation magnetization and a low coercive force and excellent in thermal endurance, and a method for producing the same. The present disclosure relates to a soft magnetic material represented by the following composition formula: FeBNi, wherein x satisfies 10≤x≤16 in at %, and y satisfies 0<y≤4 in at %, having a coercive force of 20 A/m or less, and having a coercive force characteristic decrease rate after a thermal endurance test {[(coercive force after thermal endurance test−coercive force before thermal endurance test)/coercive force before thermal endurance test]×100 (%)} of 20% or less, wherein the thermal endurance test is carried out by allowing the soft magnetic material to stand in a constant temperature oven at 170° C. in the air for 100 h, and a method for producing the same.
