Provided is a rare earth-transition metal system ferromagnetic alloy which has improved magnetic characteristics and improved thermal stability. The present invention proposes a rare earth-transition metal system ferromagnetic alloy which is characterized by having a composition represented by formula (1). R11-xR2x(Fe1-yCoy)w-zTiz (1) In formula (1), R1 comprises at least Y, and may additionally comprise Gd; R2 comprises at least Sm and may additionally comprise at least one rare earth element selected from the group consisting of La, Ce, Nd and Pr; and x, y, z and w are numbers that respectively satisfy 0 < x < 1.0, 0 ≤ y ≤ 0.4, 11 ≤ w ≤ 12.5, 1/3 ≤ z ≤ 0.7 and x ≤ 6z - 2.)
