Static properties of magnetic bubbles in garnet films with orthorhombic anisotropy
The static properties of bubbles in (110) oriented garnet films of composition (Gd, Y)3 (Fe, Mn, Ga)5O12 have been studied. The anisotropy in these films is orthorhombic with the easy axis of magnetiz...

A brief review is given of preparation, structure, and magnetization reversal in Co–P thin films for digital recording. From this, a magnetization reversal theory is developed which correctly predicts a number of observed facts about Co–P. Among these are &mA0.1 (conventional theory predicts 0.64 and 0.51, respectively), avalanche and cluster reversal mechanisms, transverse ripple, and sawtooth structure in recorded bits. Limitations to high bit and track density recording are discussed. It is suggested that lower Mr/Ms remanent squareness values may alleviate these density limiting mechanisms.
