The substitution of a small amount of Co 2+ and Ge 4+ for Fe 3+ in yttrium iron garnet causes remarkable changes of the magnetic anisotropy constants and Δ H . The magnetic anisotropy constants K 1 and K 2 of Y 3 Fe 5- x Co x /2 Ge x /2 O 12 depend strongly on temperature, and K 1 is linear to the c...
