PURPOSE:To provide compactness and high performance requested to magnetic cores and also to give higher efficiency, compact size and lightweight to various electronic devices by providing low loss in the high frequency region of magnetic core and higher coercive force thereby corresponding to the trend of turning into high frequency range for power sources and providing magnetic cores having constant magnetic permeability. CONSTITUTION:Low loss magnetic core of the present invention comprises group Fe amorphous alloy sheet band having a DC rectangular ratio (Br/Bs) of less than 50%, DC coercive force of 0.2 to 10Oe and 1MHz rectangular ratio (Br/B1) of 5 to 30%. |
