Critical Exponents of Erbium
The exponent P that describes the sinusoidally modulate d * paramagnetic phase transition crosses over from a value of 0.39 near TN to a mean field value away from TN. Electrical resistivity measurements near TN are given for the c axis and the critical behaviour is discussed. Erbium orders below its NBel temperature TN= 85 K with its spins directed along the c axis of the hcp crystal and with ...
متن کاملUniversality of Critical-point Exponents with Respect to Lattice Anisotropy*
The universality hypothesis [l] is designed to provide an answer to the question ‘On what features of an interaction Hamiltonian do criticalpoint exponents depend ? ‘. The validity of the universality hypotheses has been seriously questioned by recent results [2-41 that certain exponents for a special sort of two-dimensional Ising-like model varied smoothly with the magnitude of a fourspin inte...
متن کاملCritical Relaxation and Critical Exponents 1
Dynamic relaxation of the XY model and fully frustrated XY model quenched from an initial ordered state to the critical temperature or below is investigated with Monte Carlo methods. Universal power law scaling behaviour is observed. The dynamic critical exponent z and the static exponent η are extracted from the time-dependent Binder cumulant and magnetization. The results are competitive to t...
متن کاملCritical exponents and scaling invariance in the absence of a critical point
The paramagnetic-to-ferromagnetic phase transition is classified as a critical phenomenon due to the power-law behaviour shown by thermodynamic observables when the Curie point is approached. Here we report the observation of such a behaviour over extraordinarily many decades of suitable scaling variables in ultrathin Fe films, for certain ranges of temperature T and applied field B. This despi...
