Query: Spin polarization studies in half-metallic Co2TiX (X = Ge and Sn)
  Heusler alloys   In this paper, we investigated the Co2TiX (X = Ge, Sn) Heusler alloys by
structural, magnetic and spin polarization measurements to probe the
half-metallic nature. Alloys are synthesized using the arc melting technique,
and found to exist in L21 crystal structure with Fm-3m space group. Curie
temperature (TC) is found to be 384 and 371 K for Co2TiGe and Co2TiSn
respectively. The saturation magnetization (MS) value of 1.8 and 2.0 Bohr
magneton/f.u. are obtained at 5 K for for Co2TiGe and Co2TiSn respectively,
compared to 2.0 Bohr magneton/f.u. calculated by Slater-Pauling rule. To obtain
the spin polarization value, differential conductance curves are recorded at
the ferromagnetic/superconducting point contact at 4.2 K. The current spin
polarization (P) value of 0.63 and 0.64 are deduced for Co2TiGe and Co2TiSn
respectively. Considering the high current spin polarization and TC, these
materials appear to be promising for spintronic devices.
