La0.7-xDyxCa0.3Mn(Fe)O3 is studied extensively using Mossbauer spectroscopy, AC susceptibility, DC magnetization, and resistivity measurements. MR shows a cusp-like increase at the critical composition x = 0.10. Based on the experimental results, we provide an explanation for the high MR. Several properties of the manganite that undergo changes at this composition as x is varied are found. Our study, thus, reveals a mechanism by which CMR in excess of 108% can be obtained.
