Spin glass behavior in FeAl2

Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T f535 K and frequency-dependent susceptibility below T f . The field-cooled and zero-field-cooled magnetization diverge below T f , with hysteresis characteristic of a spin glass. A resistivity minimum just above T f is explained in terms of c...

Dynamical CPA approach to an itinerant fermionic spin glass model

Abstract. We study a fermionic version of the Sherrington-Kirkpatrick model including nearest-neighbor hopping on a ∞-dimensional simple cubic lattices. The problem is reduced to one of free fermions moving in a dynamical effective random medium. By means of a CPA method we derive a set of self-consistency equations for the spin glass order parameter and for the Fourier components of the local ...

Ageing and dynamical scaling in the critical Ising spin glass

– The non-equilibrium ageing behaviour of the three-dimensional and four-dimensional critical Ising spin glass is studied for both binary and gaussian disorder. The same phenomenology of the time-dependent scaling as in non-disordered magnets is found but the non-equilibrium exponents and the universal limit fluctuation-dissipation ratio depend on the distribution of the coupling constants. Und...
