Ultrasonic study on the hexagonal antiferromagnet Dy3Ru4Al12
Original language description
In the distorted kagome lattice antiferromagnet Dy 3 Ru 4 Al 12 with T N = 7 K, a crystal electric field (CEF) effect is expected at high temperatures. To investigate the CEF effect and the phase transition at T N , we performed ultrasonic measurements on a single-crystalline sample. At high temperatures, both the longitudinal elastic modulus C 11 and the transverse modulus C 44 increase monotonically with decreasing temperature. Below 60 K a characteristic elastic softening is observed in C 44 in contrast to C 11 with monotonic hardening down to T N . We analyzed C 44 using the Curie-Weiss-type equation and obtained a negative parameter: θ which is proportional to a quadrupole-quadrupole coupling constant under the hexagonal CEF. With further decreasing temperature, both moduli exhibit abrupt elastic hardening at T N due to a magnetostriction.
