1992 R. C. Duncan & C. Thompson in Astrophysical Jrnl.: Lett. 392 10/1 From here on, we refer to such a highly magnetized neutron star as a magnetar.

1995 Monthly Notices Royal Astron. Soc. 274 257/1 A magnetar spins down very rapidly by the usual mechanism of a magnetized, relativistic wind.

1998 Daily Tel. 30 Sept. 10/6 They believe the star is an unusual X-ray star known as SGR 1900+14—a ‘magnetar’. This is a kind of neutron star.

2003 Astrophysical Jrnl. 595 346 Young, rapidly rotating magnetars whose spin and magnetic moment point in opposite directions emit high-energy neutrinos from their polar caps through photomeson interactions.
