The temperature dependence of static magnetic bubble domain parameters have been measured in the range (0‐100°C) for a number of epitaxially grown rare‐earth garnets including the nominal compositions Er2Gd1Al.4Fe4.6012, Eu1Er2Ga.7Fe4.3012, Er1.5Eu1.5Al.4Fe4.6012, Yb2Gd1Ga.5Fe4.5012and Y1.3Eu1.7Al1Fe4012. The temperature coefficient of the bias field, H, required to collapse a bubble domain is positive at 0°C for all except the Y1.3Eu1.7garnet and it is negative or zero for all except the Er2Gd garnet at 100°C. The collapse bubble diameter decreases with increasing temperature except for the Y1.3Eu1.7garnet, where the temperature dependence is about zero. The bubble diameter decreases most rapidly in the first part of the temperature range, consistent with increases in magnetization, Ms, and decreases in domain wall energy, &sgr;w. The Eu1.5Er1.5garnet has an average bubble diameter that becomes relatively temperature independent at 100°C. In this case the negative temperature coefficient of Msnearly offsets the decreases in &sgr;w. Fixed bubble size can be obtained by having ▵Ms/Ms= ▵&sgr;w/(2&sgr;w). This condition is incompatible with ▵H = 0 except when ▵&sgr;w= ▵&sgr;Ms= 0.
