Peculiarities of Elastic Properties of RE Cobaltites RBaCo4O7 (R = Dy - Er, Y) at Magnetic Phase Transitions
Abstract:
It has been found that the temperature dependences of the Young’s modulus for rare-earth cobaltites RBaCo4O7 (R = Dy - Er, Y) exhibit significant hysteresis and irreversible effects over a wide range (80–280) K between the structural and magnetic phase transition temperatures. At the magnetic phase transition temperature, there are weak and smoothed anomalies of the Young’s modulus, which correlate with the low dimensionality and frustration of the exchange interactions in the Kagome lattice of the Co subsystem for the studied rare-earth cobaltites.
