“…For these reasons, films consisting of Tb and Co are promising for applications due to the flexibility of magnetic anisotropy which can be adjusted by varying RE concentration and modifying conditions of the sample deposition [6][7][8][9][10][11][12][13][14][15][16][17][18]. It has been shown that Tb and Co subsystems form a non-collinear so-called sperimagnetic ferrimagnetic structure [19][20][21], where the angle between magnetic moments of Co and Tb sublattices is changing from 50 to 165 • depending on the composition [22]. The compensation concentration of the Tb is x = 23 % and the angle is maximal.…”

“…Para investigar a direção preferencial de magnetização da liga CoTb e a concentração de compensação, diversas caracterizações magnéticas foram propostas. Anisotropia perpendicular da liga CoTb é identificada em amostras produzidas com outras técnicas [74,76]. A figura 2.30 a) mostra curvas de medidas da magnetização em função do campo aplicado no plano das amostras contendo diferentes quantidades de Tb e Co. As curvas de magnetização mostram boa saturação, exceto a amostra contendo 25% de térbio.…”

“…Acima dos 40% a magnetização novamente aumenta no plano e diminui na configuração perpendicular. Diante do comportamento mostrado, é razoável afirmar que amostra T b 25 Co 75 possui concentração de compensação [74,76]. A compensação da magnetização no plano é decorrente da interação dos spins dos orbitais 4f de térbio e orbitais 3d de cobalto.…”
