Pressure evolution of coplanar antiferromagnetism in heavy-fermion Ce${}_2$CoAl${}_7$Ge${}_4$

M. O. Ajeesh, A. O. Scheie, Yu Liu +4

Ce${}_2$$M$Al${}_7$Ge${}_4$ ($M=$ Co, Ir, Ni or Pd) are heavy-fermion materials and host a variety of ground states ranging from magnetism to non-Fermi liquid behavior. The Co, Ir,…
