Spin reorientation in Nd1-xYxFe11Ti

Spin-reorientation phenomena have been studied in Nd1-xYxFe11Ti compounds (x=0, 0.2, 0.4, 0.6 and 0.8). At the spin reorientation temperature, TSR, the comparing Nd and Fe anisotropy contributions are in balance. By taking the Fe anisotropy from the Y counterpart, the anisotropy of the Nd sublattice at TSR is determined experimentally. The temperature dependence of the Nd contribution to the magnetocrystalline anisotropy has been calculated by using a Hamiltonian consisting of crystal-field and exchange terms and was compared with the experimental results. A consistent set of parameters has been deduced by which the value TSR can be reproduced for the whole series of the studied compounds. © 1992.
