Exchange Bias Effect in Ni-Mn Heusler Alloys
In this chapter the exchange bias (EB) properties of bulk Mn-rich Ni50-xMn37+xSn13 (0 ≤ x ≤ 4) Heusler alloys has been discussed by changing the Ni-Mn concentration. In these alloys the exchange bias field increases with the excess Mn concentration, but exchange bias blocking temperature (TEB) decre...

| Summary: | In this chapter the exchange bias (EB) properties of bulk Mn-rich Ni50-xMn37+xSn13 (0 ≤ x ≤ 4) Heusler alloys has been discussed by changing the Ni-Mn concentration. In these alloys the exchange bias field increases with the excess Mn concentration, but exchange bias blocking temperature (TEB) decreases from 149 to 9 K. The hysteresis loop for Ni46Mn41Sn13 alloy shows a maximum shift of 377 Oe. The exchange bias property is strongly influenced by varying Ni-Mn concentration in Ni-Mn-Sn alloys then the variation of Mn/Sn. We have observed in these alloys that the TEB would show a decreasing value either by changing the Ni or Sn concentration while the Mn content is above 37% in Ni-Mn-Sn alloys. |
