3. A spin element, comprising:
a wiring;
a laminate including a first ferromagnetic layer laminated on the wiring;
a first conductive part and a second conductive part with the first ferromagnetic layer therebetween in a plan view in a lamination direction; and
a first intermediate layer which is in contact with the wiring between the first conductive part and the wiring,
wherein the wiring contains one selected from the group consisting of Au, Hf, Mo, Pt, W, and Ta as a first element,
wherein the first intermediate layer contains a second element,
wherein the first conductive part contains a third element,
wherein, when the first element is Au and the third element is Cu, the second element is one selected from the group consisting of Ag, Co, and Hf,
wherein, when the first element is Au and the third element is Ag, the second element is Co or Hf,
wherein, when the first element is Au and the third element is Co, the second element is Hf,
wherein, when the first element is Hf and the third element is Co, the second element is Al,
wherein, when the first element is Mo and the third element is Co, the second element is W,
wherein, when the first element is Pt and the third element is Al, the second element is one selected from the group consisting of Au, Ag, and Co,
wherein, when the first element is Pt and the third element is Au, the second element is Ag or Co,
wherein, when the first element is Pt and the third element is Ag, the second element is Co,
wherein, when the first element is Ta and the third element is Al, the second element is Hf,
wherein, when the first element is W and the third element is Co, the second element is one selected from the group consisting of Hf and Mo,
wherein, when the first element is Au and the third element is Ag, the second element is Pt,
wherein, when the first element is Au and the third element is Co, the second element is one selected from the group consisting of Pt, Mo, and W,
wherein, when the first element is Hf and the third element is Co, the second element is one selected from the group consisting of Au, Pt, Mo and W,
wherein, when the first element is Mo and the third element is Co, the second element is W,
wherein, when the first element is Pt and the third element is Al, the second element is Ta or Hf,
wherein, when the first element is Pt and the third element is Co, the second element is Mo or W, and
wherein, when the first element is Ta and the third element is Al, the second element is Hf.
