Cooling atoms by allowing them to equilibrate with cryogenic helium is a 
powerful tool which can be applied to any atomic species, and can produce 
very large samples of cold  atoms (T ~ 500 mK). However, magnetically 
trapping these atoms has proved challenging. As a result only atoms with 
large magnetic moments have been trapped this way, and evaporative cooling 
of these species has proved too inefficient (due to their enhanced spin 
relaxation) to reach quantum degeneracy. In this talk I will describe 
recent work in which we demonstrate that buffer gas cooling can be used to 
trap atoms with magnetic moments of 2 Bohr magnetons, of which at least one 
species is known to be Bose-condensable by evaporative cooling. This 
trapping is made possible by the use of a novel cryovalve scheme and 
magnetic traps which push the limits of superconductor technology. At 
present this approach to trapping is limited by the dynamics of helium 
adsorbates within the apparatus. I will discuss the prospects for 
overcoming these limits and extending buffer gas trapping to 1 Bohr 
magneton atoms, which would allow for the trapping of the majority of 
atomic species with a single apparatus. We have also trapped atoms with 
large magnetic moments above 1 K, greatly simplifying the cryogenics 
required to study these species.
