DESCRIPTION:Speaker: Nishat Tasnim\, MSCB candidate\nTitle: Chemical Pressu
 re Effect in the Distorted Kagome Lattice Magnetic Topological Candidates\
 nAbstract: Magnetic topological semimetals are an exciting class of quantu
 m materials in which the electronic wavefunction coupled magnetic spin con
 figuration is greatly influenced by the topology of the compounds. A proto
 typical geometrically frustrated system is the Kagome lattice\, which prov
 ides an ideal platform for exploring candidate topological semimetals due 
 to the unique interplay of geometric frustration\, spin-orbit coupling\, a
 nd strong electronic correlations. The Kagome lattice can host noncollinea
 r and noncoplanar spin textures that can induce topological magnetic state
 s which give rise to the quantum anomalous Hall effect and Weyl semimetall
 ic behavior. Recent attention has been given to the REAgGe (RE= rare earth
 ) family of materials\, with non-centrosymmetric P-62m space group\, which
  hosts a distorted Kagome lattice in the network of rare-earth ions. Here 
 we utilize chemical pressure to tune the Kagome lattice distortion and spi
 n configurations\, and in turn the nontrivial topological states. We have 
 successfully synthesized Si-doped single-crystalline REAgGe materials\, as
  determined by X-ray diffraction and SEM-EDX. The partial substitution of 
 the smaller Si atoms for the larger Ge atoms creates a positive chemical p
 ressure effect reducing the lattice dimensions. The magnetization reveals 
 a potential influence of the chemical pressure effect on the magnetic frus
 tration and field induced states in these materials. These results will ul
 timately lead to a better understanding of the interplay between magnetism
  and topology.
