                         (SGRs) are a class of pulsars understood as neutron stars (NSs) 
                         with super strong surface magnetic fields, namely B \≥ 
                         1014G, and for that reason are known as magnetars. However, in the 
                         last years, some SGRs/AXPs with low surface magnetic fields B ~ 
                         (1012-1013)G have been detected, challenging the magnetar 
                         description. Moreover, some fast and very magnetic white dwarfs 
                         (WDs) have also been observed, and at least one showed X-ray 
                         energy emission as an ordinary pulsar. Following this fact, an 
                         alternative model based on WDs pulsars has been proposed to 
                         explain this special class of pulsars. In this model, AXPs and 
                         SGRs as dense and magnetized WDs can have surface magnetic field B 
                         ~ 107-1010 G and rotate very fast with frequencies \Ω ~ 
                         1rad/s, consistent with the observed rotation periods P ~
