STABILITY OF SECOND KIND OF DUMBBELL DOMAINS SUBJECTED TO AN IN-PLANE FIELD AT DIFFERENT BIAS FIELDS 下载免费PDF全文
The softening process of the second kind of dumbbell domalns(liDs) in garnet bubble films subjected to an in-plane field Hip at different static bias field Hb was studied experimentally. It was found that when Hb is larger, the remaining percentage of IID, RIID, drops sharply at a certain Hip, and with the increase of Hb the drop occurs at lower Hip and becomes more intensive. We have confirmed that this is related to the "spontaneous-shrink" 0f IIDs, which plays an important role for the breakdown oF vertical Bloeh line chains of lids subjected to joint fields Hip and Hb . 相似文献

ANNIHILATION OF VERTICAL-BLOCH-LINE CHAINS IN THE WALLS OF ORDINARY HARD BUBBLES SUBJECTED TO JOINT STATIC BIAS FIELD AND IN-PLANE FIELD 下载免费PDF全文
For the ordinary hard bubbles(OHBs) of garnet bubble films, the annihilation of the vertical-Bloch line (VBL) chains in their walls subjected to joint static bias field Hb and in plane field Hip was experimentally studied. The curves of two critical in-plane fields, H(1)ip and H′ip, vs Hb were measured. By means of the so-called "head-cut" and "tail-cut" experiments designed in this work, it was verified that for the OHBs subjected to Hip, their VBL chains with different lengths lose VBLs and become shorter simultaneously. It was also verified that the critical in-plane fields H(1)ipand H′ip correspond to the break down of the shortest and longest VBL chains of OHBs, respectively. 相似文献

INFLUENCE OF IN-PLANE FIELD ON THE STABILITY OF VERTICAL BLOCH LINE CHAINS IN HARD DOMAINS OF GARNET BUBBLE FILMS 总被引:4,自引:0,他引:4 下载免费PDF全文
The stability of vertical Bloch line (VBL) chains was statistically studied for all three types of bard domains in garnet bubble films subjected to an in-plane field Hip. With a set of integrate data taken from seven bubble samples and with two typical figures of a sample, four main features of the behavior of VBL chains subjected to Hip were summarized. 相似文献

The magnetic properties and microstructure of triple C/CoCrTa/Ti perpendicular recording films have been studied. Magnetic measurements show that the optimal thickness of Ti underlayer is 4Ohm and that of CoCrTa is 35 nm. The optimal value of substrate temperature is found to be 400℃. A suitable Ti underlayer causes a magnetic layer to have a near-perfect hcp texture, with Co grains in the (002) preferred orientation. The film with needle-like grains is more suitable for perpendicular recording films. 相似文献
