There has been a great deal of interest in non-centrosymmetric superconductivity, mainly induced by the discovery of CePt3Si. The presence or lack of inversion has important implications for the symmetry of the superconducting state. Due to the nontrivial anti-symmetric spin-orbit coupling, because of the lack of inversion symmetry, unconventional superconducting properties have been observed in non-centrosymmetric superconductors. Recently a new family of materials has been discovered, namely the RTX3 (where R=Rare earth, T=transition metal and X=Si or Ge) and we have embarked on a program which has been investigating the magnetic and superconducting properties of the 113 family, which has resulted in a number of publications. Now we propose to investigate the new f-electron free compounds, namely CaIrSi3 and CaPtSi3 which has the potential to be an intense subject of research.
