Abstract The extension of results concerning the calculation of the external (geometric) demagnetizing factor obtained for rod like samples to strip-like ribbon samples is investigated. To match the experimental determined demagnetizing factors of strips with various length two fitting parameters have been introduced: (i) the effective width of the strip and (2) the internal demagnetizing factor. It turned out that the equivalent rod diameter calculation from the cross-section is valid up to a limited width/thickness ratio. The experimental demagnetizing factor determined from the steepness of the anhysteretic curve was greatly reduced by a uniaxial stress; where from a lower bound for the internal demagnetizing factor could be obtained. We have found that this internal demagnetizing factor is about three times larger than the geometric one for an as cast amorphous sample with Finemet composition.

条状非晶带状试样内外退磁因子的测定

摘要 研究了关于从棒状样品获得的外部（几何）退磁因子计算结果到条状带状样品的扩展。为了匹配实验确定的带不同长度的退磁因子，引入了两个拟合参数：（i）带的有效宽度和（2）内部退磁因子。结果表明，从横截面计算的等效杆直径在有限的宽度/厚度比范围内是有效的。由非磁滞曲线的陡度确定的实验退磁因子被单轴应力大大降低；从哪里可以获得内部退磁因子的下限。
