摘要：

We report Bose-Einstein condensation of two isotopes of the highly magnetic element dysprosium: Dy-162 and Dy-160. For Dy-162, condensates with 10(5) atoms form below T = 50 nK. We find the evaporation efficiency for the isotope Dy-160 to be poor; however, by utilizing a low-field Fano-Feshbach resonance to carefully change the scattering properties, it is possible to produce a Bose-Einstein condensate of Dy-160 with 103 atoms. The Dy-162 BEC reported is an order of magnitude larger in atom number than that of the previously reported Dy-164 BEC, and it may be produced within 18 s.
