Abstract
We show the possibility of having a negative phonon Grüneisen constant in the ferromagnetic state of a metal. With such behavior of Grüneisen constant, we propose phonons can be playing an important role in causing zero or negative thermal volume expansion often observed in ferromagnetic metals.
