The dependence of the magnetic ordering temperature To of Sm metal was determined through four-point electrical resistivity measurements to pressures as high as 150 GPa. A strong increase in To with pressure is observed above 85 GPa. In this pressure range, Sm ions alloyed in dilute concentration with superconducting Y exhibit giant Kondo pair breaking. Taken together, these results suggest that for pressures above ~85 GPa Sm is in a highly correlated electron state, like a Kondo lattice, with an unusually high value of To. Furthermore, a detailed comparison is made with similar results obtained earlier on Nd, Tb, and Dy and their dilute magnetic alloys with superconducting Y.
