【摘要】 <正> 磁性材料中磁畴的存在是材料技术磁化过程的物理基础。磁性材料的许多特性都与磁畴结构及其在外磁场作用下的运动变化有密切的关系。近年来发展的Fe-Ni系非晶合金具有许多优良的软磁特性。为了进一步改善这些非晶合金的低场磁特性,它们的磁畴结构已得到广泛的研究。我们用传统的粉纹技术,对淬态的Fe₄₀Ni₄₀Mo₄B₁₆非晶合金薄带自由表面上的更多还原

【Abstract】 Using conventional Bitter technique have observed the magnetic domain powder patterens on free face of the as quenching Fe40Ni40Mo4B16 amorphous metalloy thin ribbon and their variation under applied magnetic field. Vibration Sample Magnetro-meter and Impulsive Currentmeter were used to measure magnetization curve of the sheet sample and ring sample respectively. On the basis of these, we have discussed the contribution of various domains to the technical magnetization procedure and effect on the magnetic preperties.更多还原
