We have measured bubble velocity as a function of drive field for 5 micron diameter bubbles in Ne+ ion implanted
films over a 115°C temperature range from −40°C to +75°C. From this translation data the bubble mobility, μ, and dynamic coercivity, Hc, were determined. For material with a room temperature mobility of 500 cm/sec‐Oe, a mobility temperature coefficient of 1.1%/°C was calculated. Skew angle measurements were consistent with the identification of the
bubble state as the only stable wall configuration over this temperature range.
