The stannides YbPtSn and Yb₂Pt₃Sn₅

Abstract

YbPtSn and Yb

CaTMg2 and CaTCd2 (T =Rh, Pd, Pt) with YPd2Si-type Structure

“…First calcium, the noble metal and cadmium were weighed in 1 : 1 : 2.1 atomic ratios and arcwelded in small niobium tubes. The latter were placed in a water-cooled sample chamber of a high-frequency furnace (Hüttinger Elektronik, Freiburg, type TIG 1.5/300) [14] under flowing argon and annealed at 1300 K for about ten minutes, followed by cooling to 800 K within 30 min. Finally the samples were annealed for two hours at that tempera-ture, followed by quenching.…”

YPdSn and YPd2Sn: Structure, 89Y solid state NMR and 119Sn Mössbauer spectroscopy

“…Argon was purified with titanium sponge (900 K), silica gel, and molecular sieves. The tantalum tubes were then placed in the water-cooled sample chamber of an induction furnace [39] (Hüttinger Elektronik, Freiburg, Germany, Typ TIG 2.5/300). The tubes were subsequently annealed for 30 min at 1600 K and finally for 90 min at 900 K, followed by quenching.…”

From REZnSn to REZnSnH1:5 (RE = Pr, Nd) – Inducing Ferromagnetism through Hydrogenation

“…The argon was purified over titanium sponge (900 K), silica gel, and molecular sieves. The tubes were placed in a water-cooled quartz sample chamber of an induction furnace (Hüttinger Elektronik, Freiburg, type TIG 1.5/300) [28] and first rapidly heated to ca. 1450 K and kept at that temperature for 15 min.…”
