Notes:
The pseudomorphic growth of ultrathin films produces artificial structures, and with it anomalously large magnetic anisotropy energies (MAEs). Second- and fourth-order MAEs K2,K4 can be measured and analyzed. To understand the continuous (steplike) rotation of M in a spin reorientation transition (SRT), K4〈0(K4〉0) is necessary. By means of ferromagnetic resonance measurements we show that for fct Ni/Cu(001) the SRT is of second order. It is important to measure the "surface" and "volume" contribution for all MAE contributions K2,K4,... as a function of temperature. These results are compared with T=0 K first principle electronic structure calculations. © 1997 American Institute of Physics.
