摘要：

Magneto-caloric effect in an antiferromagnetic Kondo material CeNi2Al5 was sensitively observed at very low temperatures, settling the small sample of single crystal in semi-adiabatic condition. Several steep thermal variations characterizing latent heat and hysteresis between 3 and 9 T are observed, consistently with stepwise-jumps in a the magnetization curve for CeNi2Al5 below the Neel temperature T-N of 2.6 K, Three of the first-order phase transition are evidenced in H-T phase from the present measurement.
