Abstract:
We report on the magnetic properties of the RCo4Al (R: Y, Gd, Ho) monocrystalline samples. Al
substitution for Co in RCo5 results in remarkable changes of the magnetic properties not only of the Co
sublattice but also of the R sublattice. These changes include a decrease of the magnetocrystalline anisotropy
energy of the Co sublattice, a decrease of the R-Co exchange interaction and a remarkable modification of
the crystal field parameters of the R sublattice. The effects of Al substitution in RCo5 are compared with
those of B substitution.
