Complex Antiferromagnetic Order in the Metallic Triangular Lattice Compound SmAuAl$_4$Ge$_2$

Autor: Feng, Keke, Bush, Caleb, Oladehin, Olatunde, Lee, Minhyea, Baumbach, Ryan

The compounds $Ln$AuAl$_4$Ge$_2$ ($Ln$ $=$ lanthanide) form in a structure that features two-dimensional triangular lattices of $Ln$ ions that are stacked along the crystalline $c$ axis. Together with crystal electric field effects, magnetic anisotro

Field-Induced Magnetic States in the Metallic Rare-Earth Layered Triangular Antiferromagnet TbAuAl$_4$Ge$_2$

Autor: Leahy, Ian A., Feng, Keke, Dey, Roei, Baumbach, Ryan, Lee, Minhyea

Magnetic frustration in metallic rare earth lanthanides ($Ln$) with $4f$-electrons is crucial for producing interesting magnetic phases with high magnetic anisotropy where intertwined charge and spin degrees of freedom lead to novel phenomena. Here w

Magnetic Ordering in GdAuAl$_4$Ge$_2$ and TbAuAl$_4$Ge$_2$: layered compounds with triangular lanthanide nets

Autor: Feng, Keke, Leahy, Ian Andreas, Oladehin, Olatunde, Wei, Kaya, Lee, Minhyea, Baumbach, Ryan

We report the synthesis of the entire $Ln$AuAl$_4$Ge$_2$ ($Ln$ = Y, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Tm) series and focus on the magnetic properties of GdAuAl$_4$Ge$_2$ and TbAuAl$_4$Ge$_2$. Temperature and magnetic field dependent magnetization,

Magnetic properties of equiatomic CrMnFeCoNi

Autor: Elmslie, Timothy A., Startt, Jacob, Soto-Medina, Sujeily, Yang, Yang, Feng, Keke, Baumbach, Ryan E., Zappala, Emma, Morris, Gerald D., Frandsen, Benjamin A., Meisel, Mark W., Manuel, Michele V., Dingreville, Rémi, Hamlin, James J.

Magnetic, specific heat, and structural properties of the equiatomic Cantor alloy system are reported for temperatures between 5 kelvin and 300 kelvin, and up to fields of 70 kilo-oersted. Magnetization measurements performed on as-cast, annealed, an
