Hydrogen-induced modification of the local charge density in MnSb $_{2}$ Te $_{4}$

Kyriaki Samioti, Weiyan Qi, Stefano Ponzoni +14

We investigate the effects of ionic hydrogen (H $^{+}$ ) intake on the occupied and unoccupied states of MnSb $_{2}$ Te $_{4}$ , a van der Waals magnetic material. Using angle-resolved photoem…
