Abstract
Mn oxide has long been known having a large magneto resistance properties. In order to study the physical properties of the electron, high quality of single crystal is required. (La, Sr) 1 + nMnnO3n +1 (n = 2) which has two layers of Mn-O, has the largest magneto resistance properties in comparison with group n = 1, and n = ∞. In this research, manufacturing of pellet rod that will be used as a raw material for growing single crystal is studied. Then, pellet rod product is analyzed by using DTA/DTG (Differential Thermal Analysis/Differential Thermal Gravimetry) dan XRD (X-Ray Diffraction).
