Abstract
Magnetic field induced Anti-ferromagnetic (AFM) to ferromagnetic (FM) phase transition on a sample of Ce(Fe0.96Ru0.04)2 is studied by magnetic measurements before and after fast neutron irradiation performed in CIRUS reactor at BARC, Trombay. Irradiation induced material defects caused the transition to move to lower fields, increased the zero field magnetic susceptibility and suppressed the logarithmic relaxation rate in the hysteretic transition region.
