Temperature dependence of the spin and orbital magnetization density in Sm0.982Gd0.018Al2 around the spin-orbital compensation point. Taylor, J., W., Duffy, J., A., Bebb, A., M., Lees, M., R., Bouchenoire, L., Brown, S., D., & Cooper, M., J. Physical Review B, 2002.
Website abstract bibtex Nonresonant ferromagnetic x-ray diffraction has been used to separate the spin and orbital contribution to the magnetization density of the proposed zero-moment ferromagnet Sm0.982Gd0.018Al2. The alignment of the spin and orbital moments relative to the net magnetization shows a sign reversal at 84 K, the compensation temperature. Below this temperature the orbital moment is larger than the spin moment, and vice versa above it. This result implies that the compensation mechanism is driven by the different temperature dependencies of the 4f spin and orbital moments. Specific heat data indicate that the system remains ferromagnetically ordered throughout.
