测量了两种盒式磁带(γ-Fe_2O_3和 CrO_2)的矫顽力、矩形比、剩余矫顽力、矫顽力系数和旋转磁滞损失及其积分。此外,还研究了它们的电声特性。静态磁性数据可对颗粒介质的某些特性进行解释:发现,根据所加磁场的方向,CrO_2呈连贯性转动或非连贯性转动;而γ-Fe_2O_3呈非连贯性转动并与若干扇状链球面模型相背离。这可能和粒子的缺陷有关。这些缺陷都去磁磁场源。与音频特性完全一致的参量,不仅表现在矫顽力和矩形比这类众所周知参量上,而且还表现在过去往往被占统治地位的模拟记录所忽视的其它一些静态参量上。
The coercive force, squareness ratio, residual coercive force, coercive force coefficient and rotational hysteresis loss of the two kinds of magnetic tape cassettes (γ-Fe 2 O 3 and CrO 2) and their integrals were measured. In addition, their electroacoustic properties have also been studied. Static magnetic data can be used to explain some properties of granular media. It is found that CrO_2 rotates coherently or non-coherently according to the direction of the applied magnetic field. Γ-Fe 2 O 3 turns non-coherently and interacts with some fan-shaped spherical spherical models Deviation. This may be related to particle defects. These defects go to a magnetic field source. Parameters that are perfectly consistent with the audio characteristics are not only shown in the well-known parameters such as coercivity and squareness, but also in other static parameters that were neglected in the past often dominated by analog recordings.
