一、引言 在远离晶化温度的低温范围内,非晶软磁合金中所产生的结构弛豫,从而引起的磁性能变化与它们的实际应用密切相关,因为在实际应用中,软磁材料的温度稳定性是很重要的。近几年来,这个问题引起了不少人注意,对Fe基、Co基和Fe—Ni基非晶进行了一些关系到低温结构弛豫的研究。低温结构弛豫可从初磁导率的等温衰减、退火引起居里点的升高以及比热的相对变化反映出来。本文通过初磁导率等温衰减的测量, I. INTRODUCTION In the low temperature range away from the crystallization temperature, the structure relaxation in the amorphous soft magnetic alloy, resulting in changes in magnetic properties and their practical applications are closely related, because in practical applications, the soft magnetic material Temperature stability is important. In recent years, this issue has aroused a lot of people’s attention, on the Fe-based, Co-based and Fe-Ni-based amorphous some of the relationship between low-temperature structural relaxation research. Low temperature structural relaxation can be attributed to the isothermal decay of the initial permeability, the rise of the Curie point due to the annealing, and the relative change in specific heat. In this paper, the initial permeability isothermal attenuation measurement,
