      abstract     = {The SQUID magnetic measurements were performed on the GaN
                      films prepared by metal-organic vapour phase epitaxy and
                      implanted by Tb3+, Tm3+, Sm3+, and Ho3+ ions. The sapphire
                      substrate was checked by the electron paramagnetic resonance
                      method which showed a content of Cr3+ and Fe3+ impurities.
                      The samples 5 × 5 mm2 were positioned in the
                      classical straws and within an estimated accuracy of
                      10−6 emu, no ferromagnetic moment was detected in the
                      temperature region of 2–300 K. The paramagnetic
                      magnetization was studied for parallel and perpendicular
                      orientation. In the case of GaN:Tb sample, at T = 2 K,
                      a pronounced anisotropy with the easy axis perpendicular to
                      the film was observed which can be explained by the lowest
                      quasi-doublet state of the non-Kramers Tb3+ ion. The Weiss
                      temperature deduced from the susceptibility data using the
                      Curie-Weiss (C-W) law was found to depend substantially on
                      the magnetic field.},
