Quantum percolation in two-dimensional antiferromagnets.
The interplay of geometric randomness and strong quantum fluctuations is an exciting topic in quantum many-body physics, leading to the emergence of novel quantum phases in strongly correlated electron systems. Recent investigations have focused on the case of homogeneous site and bond dilution in the quantum antiferromagnet on the square lattice, reporting a classical geometric percolation tra...
متن کاملStatic Properties of Dilute Ferri‐ and Antiferromagnets
We report microscopic calculation of the static magnetic and spin‐wave properties of dilute antiferromagnetis (e.g. KMn1−x Zn xF3) and of dilute ferromagnetic garnets. The results are valid at low temperatures but are not restricted to low concentration of dilutents.

متن کاملDilute random-field Ising models and uniform-field antiferromagnets.
The order-parameter susceptibility χ of dilute Ising models with random fields and dilute antiferromagnets in a uniform field are studied for low temperatures and fields with use of low-concentration expansions, scaling theories, and exact solutions on the Cayley tree to elucidate the behavior near the percolation threshold at concentration pc. On the Cayley tree, as well as for d>6, both model...
متن کاملAnomalous magnetic thermodynamics in uncompensated collinear antiferromagnets
Monte Carlo simulations show that the net magnetization of collinear antiferromagnets (AFM) with uncompensated surfaces exhibits a unique thermodynamic behavior, with a temperature dependence unlike that of ferromagnets or of the Néel vector. The magnetization of AFM is not equal to that of its surface, even though it results from surface effects. This phenomenon appears in thin AFM films but i...
