| Abstract: | The thermal expansion and low temperature and low temperature specific heat were measured for Y1?xScxMn2. The results are discussed in terms of spin fluctuations and compared with those of Y(Mn1?xAlx)2, which show al local moment character. It is revealed that Y1?xScxMn2 is a typical nearly antiferromagnet in which giant spin fluctuations are thermally excited. |
