“…MnSi, known for its skyrmion lattice in the H-T phase diagram [15,16], is a standard system for studying QCP due to its low ordering temperature, T C ∼ 30 K [3,15,17]. Nonetheless, both pressure and doping studies established the presence of QPTs in p−x and T −x phase diagrams [3,4,9,10,[18][19][20][21][22][23][24][25][26][27][28][29]. The pressure-induced QCP in MnSi at the critical pressure p C ∼ 14.6 kbar, however, is still debated [30], as some results support the FO QPT [3,4], while others support the QCP or weak FO transition [29].…”
