What properties of an inductor change in a low temperature environment. Specifically in the -100 through -70 degrees Celsius range?

For ferrite-based inductors, mainly the magnetizing inductance drops at low temperatures. You can look at datasheets for various magnetic materials at the manufacturer's websites -- the inductance versus temperature graph will show you what you are asking about. However, the low temperature end of the graph will often not go below -20C or so...
