Effect of particle size reduction of the intermetallic compound Nd5Ge3 by ball milling has been studied by investigating the change in the magnetic and magnetocaloric properties. Ball milling is found to enhance the strength of the ferromagnetic component. An analysis based on the Arrott plots shows clear difference in the critical exponents between the bulk and the ball milled samples. Though the maximum entropy change and the relative cooling power are not altered much by the size reduction, magnetic transition temperature is affected.
