Description

The anomalous Hopkinson maximum is observed in Gd(0001) thin films at 289±1 K. This value lies about 3 K below the bulk Curie temperature. The incoherent rotations of the magnetization, which may cause the Hopkinson effect, are quenched by the contamination of the samples. The signal attenuation at 289 K after contaminating a film 80 nm thick is found to be AV∼-15.4 dB. In our observations, the sharpness of the maximum seems to be in itself a good monitor of the cleanliness of the Gd films
