Ho2Ti2O7 is recognized for its striking spin-ice behaviour as well as for prominent quantum nature. In present report, structural driven magnetic properties of the spin frustrated magnet Ho2(Ti1-xGex)2O7 (x = 0, 0.2, and 0.4) pyrochlore were examined by partially substitution of Ti by Ge. Single phasic pyrochlore superstructure was noted by X-ray diffraction and Raman spectroscopic investigations. A monotonically decreasing cell parameter along with microstrain confirms the perfectly stabilization of Ge-ion in cationic lattice. Furthermore, Raman spectroscopy also exhibits a blue shift and hardening of phonon mode due to anharmonic interaction. The electron microscopic images displayed homogenously distributed densely packed grains with decreasing grains size from ∼ 6.2 μm to ∼ 3.8 μm as on increasing × value. The weakening of ferromagnetic interaction due to enhancement of chemical pressure in Ho2Ti2O7 has been revealed by magnetic studies. The observed effect occurs due to variation in exchange and dipolar interactions among the Ho spins. No spin glass-like transition occurs even on cooling sample down to 2 K.
