“…In this case, a difference between both series is observed: while this increase is monotonous when using λ = 632.8 nm, as shown in figure 2(a), the results at λ = 1250 nm show up a change in the trend after 20-30 s for magnetic field intensities above 40 G, as illustrated in figure 2(b). These types of of trend inversion are usually related to structural transitions [24] or scattering resonances [2]. In any case, for both series, the higher the magnetic field intensity, the more pronounced the transmission changes.…”

“…Estudos prévios foram realizados determinando a transmissão da radiação através de soluções formadas por nanopartículas magnéticas na presença de campos magnéticos externos [38], verificando a variação do sinal magneto-óptico [39], a modulação [40] e a dependência temporal [41] da luz transmitida de acordo com o campo magnético aplicado, bem como a birrefringência [42] e demais fenômenos lineares [43,44]. Por outro lado, existem poucos estudos a cerca das não linearidadesópticas de nanopartículas magnéticas.…”
