The compound, LaMn2Ge2, crystallizing in ThCr2Si2-type tetragonal crystal structure, has been known to undergo ferromagnetic order below (TC=) 326 K. In this article, we report the magnetic behavior of nanocrystalline form of this compound, obtained by high-energy ball-milling. TC of this compound is reduced maginally for the nanoform, whereas there is a significant reduction of the magnitude of the saturation magnetic moment with increasing milling time. The coercive field however increases with decreasing particle size. Thus, this work provides a route to tune these parameters by reducing the particle size in this ternary family.
