FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. A magnetic element to be written using a thermally-assisted switching write operation comprises a magnetic tunnel junction formed from a tunnel barrier being disposed between first and second magnetic layers, said second magnetic layer having a second magnetisation the direction of which can be adjusted during a write operation when the magnetic tunnel junction is heated to a high threshold temperature; an upper current line connected at the upper end of the magnetic tunnel junction; and a strap portion extending laterally and connected to the bottom end of the magnetic tunnel junction; the magnetic element further comprising a bottom thermal insulating layer extending parallel to the strap portion and arranged such that the strap portion is between the magnetic tunnel junction and the bottom thermal insulating layer.
EFFECT: reduced heat loss in the magnetic tunnel junction.
