studied by resonant ultrasound spectroscopy*

LaCrGe₃ is an itinerant ferromagnet with T_C ~ 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].
