Thermodynamic and transport properties of <i>R</i>Cd<sub>3</sub>P<sub>3</sub> (<i>R</i> = La and Ce) single crystals
ORAL
Abstract
RCd3P3 (R = La and Ce) compounds crystallize into a hexagonal ScAl3C3-type structure. The magnetic Ce atoms form the triangular lattice of the two dimensional layer. Thermodynamic and transport properties of RCd3P3 were investigated by measuring the magnetization, electrical resistivity, and specific heat. The magnetic susceptibility of CeCd3P3 follows the Curie-Weiss law at high temperatures with very large negative Weiss temperature. The specific heat measurement of CeCd3P3 clearly indicates a magnetic ordering below 0.41 K with large electronic specific heat coefficient. In this talk, anomalous physical properties due to the geometrical frustration of Ce atoms will be discussed.
