It is believed that the γ- ray bursts of SGRs (type of magnetar) are due to the non-baryonic dark matter component in the form of axions. Here we have estimated the axion production and its conversion to photon. Also the energy produced in the form of soft gamma ray emission or hard x-ray in the magnetar by axion conversion is calculated .It is believed that some other non-baryonic dark matter particles may contribute to the understanding of the magnetar phenomena.
