“…These weaknesses are negated in ferromagnetic materials by the domain and domain wall enhancement mechanisms [1,6,13]. This, along with the extremely broad distribution of hyperfine fields often present in ferromagnetic materials [1,6,10,14], makes a non-resonant circuit a good choice for zero external field NMR, an example of which is shown in Fig. 2.…”

“…Although not prevalent, non-resonant transmission line probes have been used in place of tuned circuits [1][2][3][4][5][6][7][8][9][10], primarily in zero external field studies on ferromagnetic materials [1,6,7,10]. In this communication we show that in addition to its use in zero external field NMR, a simple non-resonant circuit can be applied to a variety of single and double channel experiments on non-ferromagnetic materials.…”

“…One recent study that involved quadrupolar effects in magnetic materials [59] is worth mentioning. In that study, relatively high-resolution spectra were obtained from a powdered sample of the intermetallic compound GdAl 2 in the magnetically ordered state.…”

“…Further possible work with the quadrupolar systems includes experimental implementation of the NQR proposals expounded here and combined use of the dipolar and quadrupolar interactions in solid-state NMR (because the highest available spin gives rise to at most three qubits). One recent study that involved quadrupolar effects in magnetic materials [59] is worth mentioning. In that study, relatively high-resolution spectra were obtained from a powdered sample of the intermetallic compound GdAl 2 in the magnetically ordered state.…”

“…Experimentos de oscilação quadrupolar no 59 Co, usando seleção de coerências de sétima ordem, sendo p 1 = 0,6µs, p 2 = 0,3µs, τ inicial 5 µs, com um incremento em passos de 100 ns.. a) Sinal na frequência de 60,6 MHz, e em b) a TF desse sinal.7 Conclusões e perspectivasForam estudados por RMN em campo zero os núcleos de27 Al e155,157 Gd no composto GdAl 2 , e os núcleos de 59 Co no composto GdCo 2 , na temperatura de 4,2 K, utilizando-se a sequência de dois pulsos de radiofrequência. Os sinais de RMN destes núcleos apresentaram ecos de múltiplo quantum.Os espectros obtidos dos ecos no27 Al apresentam dois picos, o pico maior em torno da frequência de 48,9 MHz e o pico menor em torno de 62,1 MHz.…”
