Title
Proposed magnetic equation of state for the three-dimensional Ising model near criticality: is the insulating ferromagnet a candidate?
Author
Abstract
In a magnetic system, consistent with Griffiths analyticity requirements one can parameterize the equation of state near criticality by writing H=râäh(è), T=rt(è) and the magnetization M=râm(è), where T is measured from the critical temperature. For the insulating ferromagnet CrBr3, the experimental data of Ho and Litster [J.T. Ho, J.D. Litster, Phys. Rev. Lett. 22 (1969) 603] is well fitted by m(è) as a linear function of è [P. Schofield, J.D. Litster, J.T. Ho, Phys. Rev. Lett. 23 (1969) 1098]. Also Ho and Litster give â=0.368, ã=1.215 and ä=4.3. Those critical experiments are very close to the recent 3D Ising results of Zhang [Z.D. Zhang, Philos. Mag. 87 (2007) 5309], namely â=3/8, ã=5/4 and ä=13/3. We therefore predict that m(è) will be proportional to è as a fingerprint of the 3D Ising Hamiltonian.
