Ferromagnetic quantum criticality: New aspects from the phase diagram of LaCrGe3

Autor: Taufour, V, Kaluarachchi, US, Bud'ko, SL, Canfield, PC

Recent theoretical and experimental studies have shown that ferromagnetic quantum criticality is always avoided in clean systems. Two possibilities have been identified. In the first scenario, the ferromagnetic transition becomes of the first order a
