Forced volume magnetostriction in Mn3.3Sn0.7C compound at room temperature

Abstract: The negative volume magnetostriction in the external magnetic field for antiperovskite Mn3.3Sn0.7C compound is discovered. Its magnetic transition temperature from paramagnetism to ferrimagnetism is 348K. The linear and volume magnetostrictions were investigated by measuring the change in length along the three-dimensional directions of the square samples at room temperature. Volume contraction was observed along all of the three directions throughout the whole magnetization. The value of volume magnetostriction is −44×10−6 at 1.5T. The magnetization saturates basically at 1.5T, however the volume magnetostriction should be higher with further increase in magnetic field. [Copyright &y& Elsevier]
