Abstract
A magnetoresistance effect element with a small element size can be provided which achieves both an increase in a thermal stability factor Δ and a reduction in a writing current Iand which improves a performance index Δ/I(μA) obtained by dividing the thermal stability factor Δ by the writing current I. The magnetoresistance effect element includes a first reference layer (B), a first junction layer (), a first magnetic layer (), a first non-magnetic coupling layer (), a second magnetic layer (), and a second junction layer (), and a film thickness of the first non-magnetic coupling layer () is 0.1 nm or more and 0.3 nm or less.
