Method for stabilizing spin element and method for manufacturing spin element

A method for stabilizing a spin element, the spin element including:

• a current-carrying part extending in a first direction;
• and an element part laminated on one surface of the current-carrying part and including a ferromagnetic material,
• the method comprising:
• applying a pulse current having a current density of 1.0×107 A/cm2 or more and 1.0×109 A/cm2 or less in the first direction of the current-carrying part,
• wherein in the case where an environmental temperature is 20° C. or higher and lower than 50° C., a pulse width of the pulse current is 1 nsec or more and 100 nsec or less, and the pulse current is applied 108 times or more at intervals of a waiting time 10 or more times longer than the pulse width of the pulse current to be applied,
• in the case where an environmental temperature is 50° C. or higher and 200° C. or lower, a pulse width of the pulse current is 1 nsec or more and 100 nsec or less, and the pulse current is applied 107 times or more at intervals of a waiting time 10 or more times longer than the pulse width of the pulse current to be applied, and
• in the case where an environmental temperature is −100° C. or higher and lower than 20° C., a pulse width of the pulse current is 10 nsec or more and 1 μsec or less, and the pulse current is applied 107 times or more at intervals of a waiting time equal to or longer than the pulse width of the pulse current to be applied.
