Usually, systems, where conduction electron acquires a berry phase due to noncoplanar spin structure, are topological hall effects. Is the geometric hall effect another name for the same effect?

Article Topological Hall Effects of Magnons in Ferrimagnets
Perhaps topological hall effect is only one of the properties of skyrmions. The geometric hall effect is more general.
