Experimental investigation of powders of the Ni2MnSn-based alloys revealed the extreme suppression of magnetization, exchange-bias effects and structural martensite transformation in powders with micron dimensions of grains. The mentioned phenomena are strongly dependent on both, the size and the shape of powder particles that were prepared in an agate mortar or in a ball mill. Results of the earlier quantum-mechanical calculation were used to discuss the observed phenomena and to assess a formation of clusters in magneto-crystalline structure of the alloys.
