I. Das et Ev. Sampathkumaran, MAGNETIZATION BEHAVIOR OF RCU(2)SI(2) (R=TB, DY, HO, ER AND TM) IN THE PARAMAGNETIC STATE, Journal of physics. Condensed matter, 6(37), 1994, pp. 120000557-120000560
The result of Dc magnetization (M) measurements on the compounds RCu(2
)Si(2) (R = Gd, Tb, Dy, Ho, Er and Tm) in the paramagnetic state up to
55 kOe are reported. In all cases, except that of Gd alloy, M is foun
d to be a non-linear function of magnetic field tending to saturate at
higher fields over a wide temperature range in the paramagnetic state
. This magnetization behaviour is found to be essentially a single-ion
ic effect, presumably arising from strong 4f quadrupolar effects.
