Colossal Terahertz Magnetoresistance from Magnetic Polarons in EuZn $_{2}$ P $_{2}$

E. Marulanda, M. Dutra, N. M. Kawahala +5

Magnetic polarons can generate colossal magnetoresistance in magnetic semiconductors, yet their terahertz electrodynamics remain largely unexplored. Here we report magneto-terahert…
