N2 - We investigate the macroscopic and microscopic physical properties of the solid solution of Ce1-xPrxAlGe. The series tunes from CeAlGe with its multi-kâ -structure and a major moment in the ab plane, to PrAlGe with an easy c-axis ferromagnetic ground state coexisting with a low density of nanoscale textured magnetic domain walls. Using AC, DC susceptibility, resistivity, specific heat, muon spin relaxation/rotation, and neutron scattering we analyze the magnetic ground state of the series. We provide further evidence supporting our previous claim for spin-glass-like properties in pure PrAlGe. With the introduction of Pr to CeAlGe the finite magnetic field required to stabilize the topological multi-kâ -magnetic phase for x=0 becomes suppressed. The crossover between the two end-member ground states occurs in the vicinity of x=0.3, a region where we further anticipate the field-induced topological magnetic phase for x<0.3 to become the zero field ground state.
