First claim
Opening claim text (preview).
What is claimed is: 1 . An iron-aluminum-terbium based magnetic alloy material, comprising a total of 70 atomic percent or more of three elements of iron, aluminum, and terbium. 2 . The magnetic alloy material according to claim 1 , wherein a composition ratio of aluminum is equal to or more than 20 atomic percent and equal to or less than 35 atomic percent in three elements of iron, aluminum, and terbium. 3 . The magnetic alloy material according to claim 1 , wherein a composition ratio of terbium is equal to or more than 5 atomic percent and equal to or less than 20 atomic percent in three elements of iron, aluminum, and terbium. 4 . The magnetic alloy material according to claim 1 , wherein a composition ratio of iron, aluminum, and terbium is 6:2:1 in three elements of iron, aluminum, and terbium. 5 . A thermoelectric conversion element, comprising a power generation body including the magnetic alloy material according to claim 1 , wherein the power generation body has a plate-like shape including two main surfaces facing each other, and the magnetic alloy material is magnetized in an in-plane direction of the two main surfaces. 6 . A thermoelectric conversion element, comprising a power generation body having a structure in which a first magnetic layer including the magnetic alloy material according to claim 1 and a second magnetic layer in which a spin Seebeck effect appears by application of a temperature gradient are laminated. 7 . A thermoelectric conversion element, comprising a power generation body formed of a magnetic network including the magnetic alloy material according to claim 1 , and a magnetic particle that is dispersed inside the magnetic network and in which a spin Seebeck effect appears by application of a temperature gradient. 8 . A thermoelectric conversion module, comprising a power generation body having a pipe structure including the magnetic alloy material according to claim 1 . 9 . The thermoelectric conversion module according to claim 8 , wherein the power generation body having the pipe structure is magnetized in a circumferential direction centered on a pipe axis. 10 . The thermoelectric conversion module according to claim 8 , further comprising at least two electrode terminals disposed at an interval along a pipe axial direction on an outer surface of the power generation body having the pipe structure.
