“…In a crystalline environment, the degeneracy of the ground-J multiplet is partially lifted, and in the specific case of the Sm 3+ ions, the crystalline electric field and the exchange field can induce admixture of the higher J-multiplets (J = 7/2, 9/2) into the ground J-multiplet (J = 5/2) 2-5 . Such circumstances not only substantially reduce the magnetic moment/Sm 3+ ion [6][7][8][9] , but, also make the orbital and spin contributions undergo different thermal evolutions 4,5,8,10,11 .…”
