The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

Publisher Summary This chapter discusses percolation theory as well as spin-glass
phenomena, the former of which is used to understand subjects as diverse as fluid flow in …

The recently discovered kagome metal series A V3Sb5 (A= K, Rb, Cs) exhibits topologically
nontrivial band structures, chiral charge order and superconductivity, presenting a unique …

As established in the very early work of Edwin Hall, ferromagnetic conductors have an
anomalous Hall conductivity contribution that cannot be attributed to Lorentz forces and …

The kagome-lattice quantum Heisenberg antiferromagnet is studied by a large-N expansion
based upon groups with symplectic Sp (N) symmetry. Two distinct types of ground states are …

We have performed thermodynamic and neutron scattering measurements on the S= 1/2
kagomé lattice antiferromagnet ZnCu 3 (OH) 6 Cl 2. The susceptibility indicates a Curie …

The current state of efforts to understand the phenomenon of geometric magnetic frustration
is described in the context of several key materials. All are transition metal oxides which …

We study the ground-state and low-energy properties of classical vector spin models with
nearest-neighbor antiferromagnetic interactions on a class of geometrically frustrated …

We report on a systematic study of two-dimensional, periodic, frustrated Ising models with
quantum dynamics introduced via a transverse magnetic field. The systems studied are the …

Recently, the most intensely studied objects in the electronic theory of solids have been
strongly correlated systems and graphene. However, the fact that the Dirac bands in …
