Critical exponents of FeBO3

AIP Conference Proceedings, 1975
A sample of FeBO3 containing 1‐5 μm diameter platelets was prepared. Magnetic measurement were made using a vibrating coil magnetometer and fields of 0.1 to 5 kOe. Data analysis included the effect of crystallite alignment and corrections for the small demagnetizing field. The Curie temperature was found to be 347.85±0.2 K.

The Crossover Region Between Long-Range and Short-Range Interactions for the Critical Exponents

, 2014
It is well know that systems with an interaction decaying as a power of the distance may have critical exponents that are different from those of short-range systems.

Surface Critical Exponents in Terms of Bulk Exponents

Physical Review Letters, 1977
The surface exponents associated with critical phenomena in semi-infinite systems are derived exactly in terms of bulk exponents. Results are ${\ensuremath{\gamma}}_{1,1}=\ensuremath{\nu}\ensuremath{-}1$, ${\ensuremath{\gamma}}_{1}=\ensuremath{\nu}+\frac{(\ensuremath{\gamma}\ensuremath{-}1)}{2}$, ${\ensuremath{\beta}}_{1}=\frac{(3\ensuremath ...

Ising Critical Exponents on Random Trees and Graphs

Communications in Mathematical Physics, 2012
We study the critical behavior of the ferromagnetic Ising model on random trees as well as so-called locally tree-like random graphs. We pay special attention to trees and graphs with a power-law offspring or degree distribution whose tail behavior is ...

Critical viscosity exponent for classical fluids

Physical Review E, 2005
A self-consistent mode-coupling calculation of the critical viscosity exponent z(eta) for classical fluids is performed by including the memory effect and the vertex corrections. The incorporation of the memory effect is through a self-consistency procedure that evaluates the order parameter and shear momentum relaxation rates at nonzero frequencies ...

A Dirichlet problem involving critical exponents

Nonlinear Analysis: Theory, Methods & Applications, 1995
The goal of this work is to find a nontrivial solution of the equation: \[ - \Delta_p (u) \equiv - \text{div} \bigl( |Du |^{p - 2} Du \bigr) = |u |^{r - 2} u + \lambda g(u), \quad u > 0 \text{ in } \Omega, \quad u = 0 \text{ on } \partial \Omega, \tag{1} \] where \(\Omega\) is a bounded and smooth domain of \(\mathbb{R}^N\).

Critical exponents in four-fermion theories

Physical Review D, 1994
We find the complete set of critical exponents for the simplest four-fermion theory in all dimensions $2ld\ensuremath{\le}4$. They satisfy the hyperscaling relations.

Probe independence of hyperfine critical exponents

Physical Review B, 1976
The critical exponent $\ensuremath{\beta}$ for magnetically ordered materials has been obtained from a variety of hyperfine experiments, such as nuclear magnetic resonance, perturbed angular correlations, and M\"ossbauer effect. In this paper we discuss probe disturbance effects on hyperfine measurements of $\ensuremath{\beta}$.
