Abstract EN
Low-temperature specific heat (SH) is measured on the postannealed Ba(Fe1−xNi x)2As2 single crystal with x = 0.058 under different magnetic fields.
The sample locates on the overdoped sides and the critical transition temperature T c is determined to be 14.8 K by both the magnetization and SH measurements.
A simple and reliable analysis shows that, besides the phonon and normal electronic contributions, a clear T 2 term emerges in the low temperature SH data.
Our observation is similar to that observed in the Co-doped system in our previous work and is consistent with the theoretical prediction for a superconductor with line nodes in the energy gap.
