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…

Pressure tuning of putative quantum criticality on YbV6Sn6

P. C. Sabino, L. Mendonça-Ferreira, J. G. Dias +5

YbV $_{6}$ Sn $_{6}$ is a recently discovered heavy-fermion compound that orders at T $_{N} \approx 0.4$ K and exhibits a magnetic field-tuned quantum critical point at $H \approx 10$ kOe. In…

Synthesis and anisotropic magnetism of singlecrystalline GdPt2Si2

Gustavo Gomes Vasques, Mateus Dutra, Pedro Caetano Sabino +4

Single crystals of GdPt $_{2}$ Si $_{2}$ were grown using the Sn flux method, crystallizing in the CaBe $_{2}$ Ge $_{2}$ -type tetragonal structure with space group $P 4/ nmm$ . Electrical resistivi…

Spin Dynamics and Light-Induced Effects in EuZn $_{2}$ P $_{2}$

M. Dutra, G. G. Vasques, P. C. Sabino +8

The magnetic spin dynamics and optical properties of EuZn $_{2}$ P $_{2}$ are studied. Single crystals grown by the Sn-flux method crystallize in the $P 3 m 1$ (No.~164) space gro…
