Kagome lattice magnets are an interesting class of materials as they host topological properties in their magnetic and electronic structures. YMn₆Sn₆ is one such compound in which a series of competing magnetic phases is stabilized by applied magnetic field, and both an enigmatic topological Hall effect and a Dirac crossing close to the Fermi energy have been realized. This material also shows a magnetization induced Lifshitz transition and evidence of an efficient charge-spin coupling in one of the magnetic phases, namely the fan-like phase. Tuning the magnetism, and thus the interplay with the electronic states, opens new avenues into precise control of the novel properties. Here, we demonstrate the extreme sensitivity of the magnetic phases in YMn₆Sn_6-xGe_xvia magnetization and magnetotransport measurements. The high degree of sensitivity to small doping concentrations provides great potential for engineering the magnetic phases and associated electronic properties in this family of rare-earth Kagome magnets.
