In correlated electron materials, electrons often self-organize and form a variety of patterns with potential ordering of charges, spins, and orbitals, which are believed to be closely connected to many novel properties of these materials including s

Structural behavior of the kagome antiferromagnet TmBaCo4O7: Neutron diffraction study and group-theoretical consideration

Autor: Khalyavin, DD, Chapon, LC, Radaelli, PG, Zheng, H, Mitchell, JF

The first-order structural phase transition at TS ∼240 K in the extended kagome antiferromagnet TmBaCo4O7 has been studied by neutron powder diffraction. In order to comprehend the microscopic origin of the transition, a detailed symmetry analysis
