“…13 Both isothermal magnetization and susceptibility as a function of temperature were measured. The isothermal magnetization curves were recorded at magnetic fields in the range corresponding to μ 0 H = 0 to 10 T, while the temperature-dependent magnetic susceptibility χ (T ) was measured at μ 0 H = 0.5 T.…”

Magnetic and Mössbauer spectral study of ErFe11Ti and ErFe11TiH

“…The isothermal magnetization curves were obtained at 5 and 300 K with the extraction method 24 in a dc field of up to 7 T. The saturation magnetization values have been derived, as discussed 24 earlier by extrapolation to zero field of the magnetization results obtained in fields above 4 T. The lowtemperature ac magnetic susceptibilities were obtained on a computer controlled mutual inductance susceptometer 25 at an exciting field of 10 Ϫ4 T and a frequency of 120 Hz. A lock-in amplifier was used to measure the complex susceptibility, ac ϭЈϪ jЉ, where Ј is the initial susceptibility, a quantity which is related to the variation in the sample magnetization, and Љ is nonzero if magnetic energy is absorbed by the sample.…”

“…The magnetic measurements have been recorded by the extraction method [6] in a continuous field of 0.01, 0.1 and 1 T. A detailed description of the experimental set up can be found elsewhere [6].…”
