The present disclosure concerns a magnetic elements (1) to be written using a thermally-assisted switching write operation comprising a magnetic tunnel junction (2) formed from a tunnel barrier (22) being disposed between first and second magnetic layers (21, 23), said second magnetic layer having a second magnetization which direction can be adjusted during a write operation when the magnetic tunnel junction (2) is heated at a high threshold temperature; an upper current line (4) connected at the upper end of the magnetic tunnel junction (2); and a strap portion (7) extending laterally and connected to the bottom end of the magnetic tunnel junction (2); wherein the magnetic device (1) further comprises a bottom thermal insulating layer (28) extending substantially parallel to the strap portion (7) and arranged such that the strap portion (7) is between the magnetic tunnel junction (2) and the bottom thermal insulating layer (28), for lowering heat losses in the magnetic tunnel junction (2) during the write operation as compared to with the magnetic tunnel junction (2) without the bottom thermal insulating layer (28). The magnetic element allows for reducing heat losses during the write operation and has reduced power consumption. |
