The dependence of collapse field, velocity, and trajectory angle on in‐plane field has been measured on a set of (YLaEu)3(FeGa)5O12 films ion implanted at energies ranging from 25 to 200 KeV. At zero inplane field, the S number was always ∠1. At increasing values of in‐plane field, S was found to increase, then undergo a sharp downward transition, and eventually decrease to zero. The transition occurred at a value of in‐plane field for which the collapse field was a minimum. These results are interpreted in terms of a bubble containing two Bloch points with good agreement between the model properties and the data.
