Anisotropic transport and magnetic properties, and magnetic-field tuned ground states of CeZn$_{11}$
ORAL
Abstract
We have studied the electrical, magnetic, and thermal properties of single crystals of CeZn$_{11}$ by the means of magnetization, resistivity, heat capacity, and thermoelectric power. The compound exhibits an antiferromagnetic long-range order below 2.0 K. The zero-field temperature dependent resistivity of CeZn$_{11}$ is similar to that of other strongly correlated, Kondo lattice, compounds. $T_N$ is suppressed with the applied magnetic field and disappears for $H\sim$47.5 kOe ($H\|$[110]) and $H\sim$ 120 kOe ($H\|$[011]). Temperature-dependent resistivity for $H\|$[110] shows sub-linear behavior up to 2.5 K for $H$=45 kOe, followed by Fermi liquid behavior for limited range of temperatures ($T<$1.1 K) and fields (47.5 kOe$\leq H\leq$60 kOe). The $\it H-T$ phase diagrams for $H\|$[110] and $H\|$[011] will be discussed.
