The static and dynamic characteristics of the VBLs and their stability have been studied for a typical 1 μm bubble material. The measured static bubble collapse fields Hc ranged from 472 to 544 Oe, with discrete distributions. The maximum value of Hc and the width of the bias pulse field necessary for dynamic bubble collapse were reasonably explained by assuming the critical hard wall energy of 1.1 erg/cm2. The VBLs were found to be stable for the 107applications of a series bias pulse field of 80 Oe amplitude at room temperature.
