Temperature dependence of the elastic properties of LaCrGe<sub>3</sub> studied by resonant ultrasound spectroscopy

ORAL

Abstract

LaCrGe3 is an itinerant ferromagnet with TC ~ 85 K, fragile magnetic order and a rich and complex temperature – pressure – magnetic field phase diagram [1,2]. We will report a study of the temperature – dependent elastic properties of LaCrGe3, through its ferromagnetic transition, using resonant ultrasound spectroscopy. The overall behavior will be discussed together with other thermodynamic and transport measurements. Experimental elastic constants will be compared with the results of recent first principles band structure calculations [3].
