Abstract
Spin ice compounds (SICs) are the frustrated magnetic materials which are used in nuclear reactor control system and semiconductor electronic circuits. Photon interaction parameters such as the effective atomic number, Zeff, and the effective electron density, Neff, for SICs such as Dy2Ti2O7, Dy2Sn2O7, Ho2Ti2O7 and Ho2Sn2O7 have been computed at photon energies from 10 keV to 100 GeV. The Zeff of the spin ice compounds is approximately constant in energy range 0.3–4 MeV where Compton scattering is the main photon interaction process. The Zeff increases sharply below 0.3 MeV due to photoelectric absorption process and above 3 MeV due to pair-production process. The well type structures of Zeff and Neff for HSO and DSO have been observed in the photon energy range 30–60 keV due to involvement of k-shell electron in the interaction. Dy2Sn2O7 and Ho2Sn2O7 are suitable materials for gamma shielding.
