In this manuscript, we propose a method to prepare small flakes of DyCu2. Ontop of that we also report on the magnetocaloric effect and nature of magnetictransition of a strongly anisotropic DyCu2 in its low dimension. Magnetizationmeasurements were carried out in the temperature range of 5 to 100 K and up tothe maximum magnetic field strength of 50 kOe. Magnetic entropy change delta SMis estimated using the well known Maxwells equations and is found to be 4.31 Jper kg K. Indeed, the delta SM peak broadened marginally compared with its bulkDyCu2 and such a broadening can be attributed to significant increase in thetotal grain boundary volume. As these small flakes consists larger delta SMvalues at temperatures higher than the Neel temperature TN, one can use them asa magnetic refrigerant material in a broad temperature range. We also plottedthe M2 vs H by M in order to find the nature of magnetic transition. Arrottplots infer that indeed there exists nonlinearity in M2 vs H by M behavior andsuch nonlinear behavior is ascribed to the random anisotropy or a random fieldthat is present in the system.
